The aim of this study is to explore (non)morphological processes that native speakers of Jordanian Urban Arabic and Jordanian Rural Arabic use to expand their own lexicon. Three Jordanian female respondents were interviewed to collect data. The data consist of transcriptions of recorded tokens, which were categorised into groups according to the (non)morphological processes that they undergo. Findings of the study show that there is a number of (non)morphological processes that native speakers of Jordanian Urban Arabic and Jordanian Rural Arabic use to enlarge their own lexicon. The morphological processes include affixation, suppletion, conversion, and vowel mark placement. The present study has also explored a number of non-morphological processes which include univerbation, borrowing, and word creation.
