The boy's book ( Definite article + Third person possesive pronoun)

If you want to use the possesive pronoun for the third person, just add either -iisu for a male subject, or -eedu for a female subject. E.g. 'magaciisu' (his name), 'borsadeedu' (her handbag). 

But what if you want to say 'the boy's book', or 'the girl's handbag'? You do this by using the definite article and then using the possesive pronoun. So,

Wiilka buuggiisa - The boy's book (lit: 'The boy his book')
Gabadhdha borsadeeda - The girl's handbag (lit: 'The girl her handbag)
Ninka naagtiisa - The man's wife
Macallinka qalinkiisa - The teacher's pen
