"Pima afya yako"

Translation: Check your health

[ZanninaMargariti]

Why not pime??

[AGreatUserName]

The direct imperative without an object prefix is simply the verb stem with the ending unchanged, so, in this case, pima.

If you add an object prefix, then you need to change a final "a" to "e", for example ipime "check it".

The "e" ending is also used for the subjunctive, which always has a subject prefix.

Upime = You should check.
Uipime = You should check it.
Usipime = You shouldn't check / Don't check.
Usiipime = You shouldn't check it / Don't check it.

[SimonandNe]

upime would be the polite imperative.

[GabrielleDoecke]

The correct solution has "cheque" your health! They got their English homophones mixed up!

[PhilaNtaba]

How would one "cheque" their health?

Seems to be fixed now (Mar 2018).

[MorwennaGr1]

examine your health should be accepted.
