The aim of this thesis is to investigate lexical replacement processes from several complementary perspectives. It does so through three studies, each with a different scope and time depth. The first study (chapter 3) takes a high time depth perspective and investigates factors that affect the rate (likelihood) of lexical replacement in the core vocabulary of 98 Indo-European language varieties through a multiple linear regression model. The chapter shows that the following factors predict part of the rate of lexical replacement for non-grammatical concepts: frequency, the number of synonyms and senses, and how imageable the concept is in the mind. What looks like a straightforward lexical replacement at a high time depth perspective is better understood as several intertwined gradual processes of lexical change at lower time depths. The second study (chapter 5) narrows the focus to seven closely-related Germanic language varieties (English, German, Bernese, Danish, Swedish, Norwegian, and Icelandic) and a single semantic domain, namely color.  The chapter charts several lexical replacement and change processes in the pink and purple area of color space through experiments with 146 speakers. The third study (chapter 6) narrows the focus even more, to two generations of speakers of a single language, Swedish. It combines experimental data on how the two age groups partition and label the color space in general, and pink and purple in particular, with more detailed data on lexical replacement and change from interviews, color descriptions in historical and contemporary dictionaries, as well as botanical lexicons, and historical fiction corpora. This thesis makes a descriptive, methodological and theoretical contribution to the study of lexical replacement. Taken together, the different perspectives highlight the usefulness of method triangulation in approaching the complex phenomenon of lexical replacement.

With data from the Corpus of Historical American English, this study charts the semantic development of lame, crippled, handicapped, and disabled from the 1900s to the 2010s. Using both qualitative concordance line examination and frequency data, it attempts to determine what types of change have occurred in American English (as represented by COHA) within each adjective. Further, the study isolates each adjective’s ‘human disability’ reference usage from its total frequency to determine a history of how people with disability have been described in the data period. The study finds that the trends of the adjectives’ ‘disability’ reference sense quite cleanly follows a euphemism treadmill (Pinker, 2007: 320): lame’s descent cooccurs with crippled’s ascent, which is also true for crippled and handicapped, and handicapped and disabled, with some overlap. Notable form-centric developments are the emergence of an abstract sense of lame through a metaphorical application of the ‘disability’ sense; the steady frequency of a metaphorical application of crippled to describe ‘damage’ in an inanimate noun referent; the rise of handicapped’s metonymical handicapped parking, against its general trend; and disabled’s semantically narrowed emergence as the most frequent lexical item after the US civil rights movement.

With respect to its troubled past Northern Ireland has constantly been a field of interest, academic research and discourse. Certain periods in this past, like for example the “Troubles” (a time of violent struggle that began in 1969/70), sooner or later tend to create a particular approach towards language usage. As research has already been carried out on the “Troubles” and its language usage the question now remains in how far the application of lexical items would be changing through the impact of the so called peace process. Examining the language use surrounding this process a wide range of phenomena in the field of politics and social affairs but also in society could be analysed and discussed, assuming that change for some reason developed here. Investigating such circumstances further this empirical interdisciplinary study in the shape of a corpus analysis addresses the presumed language change in Northern Ireland by employing news texts (Belfast Telegraph, BBC Northern Ireland and An Phoblacht) of the period from 1995 to 2009 (i.e. before and after the Good Friday Agreement a negotiated settlement between Catholics and Protestants in 1998) for the analysis to attempt to establish a link between changing semantic and lexical units, and to some extend to even find a relation to alleged gradual social change. The evaluation is based on a qualitative and quantitative analysis of thematically pre-selected keywords in the areas of politics, social affairs, and society. Generally it could therefore be concluded that change – though marginal in numbers – appears perceivable. Despite a detailed examination and evaluation (qualitative and quantitative) it needs to be pointed out, however, that the findings of correlating social and linguistic variables could in the end only imply a kind of relation – contrary to the expectations in the beginning. Perhaps, in some cases, gradual change could be illustrated like for example with the name change of the police (RUC to PSNI) or changed social terminology. Nevertheless this study created an important contribution of research on post-“Troubles” Northern Ireland as it brings this statelet back into focus on the one hand and in addition prompts questions on the challenges of future language usage in societies that experienced violent conflict on the other.

Jede lebendige Sprache ist durch ihren Gebrauch ständigem Wandel unterworfen, der jede Ebene der Sprache betreffen kann – von der Phonologie über die Semantik bis hin zur Grammatik. Die vorliegende Arbeit hat es sich zur Aufgabe gemacht, den semantischen und lexikalischen Wandel des Ägyptischen zu beleuchten. Das Ägyptische ist in seinen verschiedenen Sprachstufen über mehr als vier Jahrtausende hinweg zu verfolgen, und gehört damit zu den am längsten bezeugten Einzelsprachen der Menschheitsgeschichte. Dies und die gute Quellenlage des Ägyptischen machen es zu einem prädestinierten Gegenstand für diachrone Untersuchungen. Nach einer quantitativen Erhebung der Lexeme eines ausgewählten Textkorpus’, der die Grundlage der Arbeit liefert, wurden im zweiten Teil der Dissertation vier Wortfelder exemplarisch auf ihr Wandelverhalten hin untersucht. Diese Wortfelder, Verwandtschafts- und Körperteilbezeichnungen sowie Wahrnehmungsverben und kognitive Verben, gehören zum Grundvokabular einer jeden Sprache, was die Vergleichbarkeit der Ergebnisse garantieren soll. Neben der Beschreibung konkreter Wandelphänomene wurde dabei Fragen nach dem Ablauf, dem Umfang und den Typen von semantischem und lexikalischem Wandel im Ägyptischen nachgegangen. Ziel war es unter anderem, generalisierbare Aussagen zu treffen, die für die allgemeinen Fragestellungen der Sprachwandelforschung, der Diachronen Semantik und der Historischen Linguistik von Relevanz sind, indem sie mit Ergebnissen früherer Untersuchungen zu den verschiedensten Sprachen verglichen bzw. zu ihrer Überprüfung herangezogen werden können. Als Ergebnis der Untersuchung konnten neben der Beschreibung interessanter Einzelbeobachtungen schließlich einige Regularitäten des semantischen und lexikalischen Wandels des Ägyptischen aufgestellt werden. Diese wurden zum Teil bereits durch andere Sprachen bestätigt und können nach weiterer Überprüfung möglicherweise als universale Tendenzen des semantischen Wandels formuliert werden. / Every spoken language is subject to constant change due to its use. This change can affect every level of the language, from phonology to semantics to grammar. The present dissertation is set out to illuminate the semantic and lexical change of the Egyptian language, which can be followed over four thousand years and is therefore one of the longest attested languages of mankind. This and its excellent state of sources make it the ideal subject of a diachronic study. After a quantitative analysis of the lexemes of a carefully chosen set of texts, which provides the foundation of the study, the main part of the dissertation examines four semantic fields with regard to its mode of change. These semantic fields, kinship terms and terms for body parts as well as verbs for cognition and perception, are part of the basic vocabulary of every language, which guarantees the comparability of the results. In addition to the description of individual processes of change, the paper pursues questions of the course, the range, and the types of semantic and lexical change of the Egyptian language. The intention was to form general statements which are of relevance to questions of the study of language change, the Diachronic Semantics as well as the Historical Linguistics, by serving as comparison as well as verification to studies of other languages. As a result of the present paper, some general regularities of the semantic and lexical change of the Egyptian language were established, in addition to the observation of some interesting individual processes of language change. These regularities were already partially confirmed by observations made in other languages and could, after further examination, turn out to be universal tendencies of semantic change.
