Excerpt from Folk-Lore From The Cape Verde Islands, Vol. 2 (Classic Reprint)
One generally finds a single word for the personal pronoun, be it nominative, accusative, or dative: me or m' stands for ea, mim, me, and sometimes for the possessive adjective mea and min/za.
Mi is sometimes found for mim and min/za. But 'm sounded as in French un is the common form of the first person singular. In the nominative the sound is written 'm, (mi)m; in the accusa tive, as a concession to the eye of the Portuguese reader, m', m(e). The third person singular, accusative and dative, is written in the contracted form in which it is used; e.g., comprei! For comprá-lo, comprei-la, or comprá-l/ze.
Nu or n' is used for nos, nós, and for the possessive adjective nosso or nossa, nossas.
