One of the characteristics of any language is its ability to grow. Also, it is mandatory for any
language to be comprehensible, communicable and linguistically functional. It is also observed
that some of Yorùbá words are gradually losing their original phonological and morphological
status as a result of dialectal interference. This research work sets out to identify these words and
discuss how this interference affects the phonological and morphological status of the selected
Yoruba words and its effects on Yoruba standard language. The study employs the phonological
and morphological theories to critically examine the selected Yorùbá words with dialectal
interference. Though, Yoruba dialects are culturally and linguistically beautiful and embraceable,
thus, this study admonishes the speakers of Yorùbá language and Yorùbá scholars on the need to
maintain the linguistic status quo of Yorùbá phonology, morphology and orthography as
prescribed by the Yoruba standard language so as to avoid ambiguity as well as phonological and
morphological errors. The study concludes by making recommendations and admonishing Yorùbá
speakers in general to improve more on speaking and writing standard Yorùbá language.
