1.0 GENERAL INTRODUCTION
This research work would be carried-out in one of the four (4) major areas of linguistics (phonology). Phonology is the systematic study of sounds system of a language. However, the research work does not include all aspects of phonology rather it will be restricted to two important phonological processes in Hausa language: Labialization and Palatalization which are secondary articulations in Hausa language. Dustan, E (1996).
It is obvious that Hausa is the most widely spoken language among its different users in northern part of the country among different dialects such as Kananci, Sakkwatanci, Katsinanci, Kabanci, Zamfaranci, and the like. Dustan, E (1996).
Mu’azu (2005), sees labialization as a secondary articulation in which lip rounding is added to a non-labial sound as in the case of articulation of /kw/, /ƙw/, and /gw/ consonants which are specifically referred to as labialized velars. Palatalisation is a verbal noun derived from the verb to “palatalized” means to add a palatal articulation (raise the front of the tongue towards the hard palate) to a non-palatal consonant under certain conditions. Palatalization is also a secondary articulation; there may be modification which adds an in colouring to the sound. The question now is, what are the kinds of consonants and under what conditions are they palatalized? Generally speaking, consonants that are commonly palatalized in Hausa under particular circumstances are twofold, namely the alveolars /s/, /t/, /d/ and /z/, and the velars /w/, /k/, /ƙ/, and /g/.

1.1 STATEMENT OF THE PROBLEM
Hausa language is spoken in Nigeria particularly in the Northern region of the country since time immemorial. It is no doubt, the most widely spoken language in Nigeria. In particular the language is spoken as L1 in many states of the Northern Nigeria which include: Kano, Katsina, Daura, Zamfara, Kebbi and etc. This study examines two (2) phonological processes: (labialization and palatalization) in Hausa language. It is part of the study to identify the nature and conditions for each of them in Hausa language.
