PhD (English) / Department of English / Learning English as a second language by the South African learners studying English First Additional language (EFAL) presents many challenges, such as poor competence in the use of tenses, because of the differences between the learners’ first and second languages. In Grade 11, which is the closest point with regard to the exit point to institutions of higher learning or to the workplace, learners still display certain discrepancies in the mastery of the English tenses. These discrepancies occur despite the fact that in many South African schools, English is used as a medium of instruction and is learnt as a First Additional Language. The study used pragmatist research paradigm to collect data from the sampled respondents. The study answered four questions based on the types of errors committed in the use of tenses, the description and evaluation of errors, establishment of the causes of errors; and remedial measures for the errors committed by the Grade 11 EFAL learners in the use of tenses. Thus, Error Analysis Approaches were applied to find learners’ errors committed in written tasks. The types of errors identified include the inter-lingual transfer, overgeneralisation, false concept hypothesised, inadequate learning, fossilisation and ignorance of rule restrictions. Learners’ errors occurred in the domains of the simple present, the simple past, the present perfect and the past perfect tenses, regular and irregular verb inflectional morphemes, third person singular and plural subjects; and subject-verb agreement. In essence, this study reveals that some learners still face challenges in the use of tenses. Thus, remedial measures were suggested for the errors committed. / NRF
