why is it мои and not моя ?

[JonBell18]

мои shows that what comes after it (the towels) is plural

[Fabio44431]

Why not полотенця ?

[Tang_Lewgs]

Because combination "ця" is forbidden. So does г, к, х, ж, ц, ч, ш, щ+ ы, ю, я(except цы) .

[PaolaArauj6]

Why not мой полотенца?

[andriluik]

In Russian 'мой' (also моя and моё) means 'my' and used only when talking about on certain object -
Мой кот - my cat
Моя тарелка - my plate
Моё имя - my name (имя is an exeption, all words ending with -мя are neuter, usually neuter words end with -о, like место (place) or -e like солнце (sun)).

In your sentance мой is masculine singular, but полотенца is neuter plural.

Мои is used with all plural objects asking what? with some exeptions

Мои Полотенце

[JanisaChatte]

It would be "моё полотенце" since "towel" is a neuter noun.

I wrote this and was told i had a typo, should have been marked as a mistake. Typo should not be an option for multiple choice questions.

Мая полотенца
