Just a simple question as I am not sure of the right form. What is the Russian diminutive of mouse? мышонок ?

    Just wondering why you've decided that ш will mutate to ж?

  • Eastern slavic languages have consonant mutation in some words/roots, but it's like к-ч-ц, г-ж-з, х-ш-с.

Well, "мышонок" is a baby mouse so you were close, but strictly speaking diminutive is мышка which is a small mouse.

    @Oliver мышка because in Russian a mouse defaults to feminine - мышь Jul 4, 2019 at 21:20

    The answer is perfectly correct, but I'd like to add that it is a quite common reference to a beloved woman: "мышка моя". Very similar to "киса"(means кошка, кошечка), which is very popular amongst young men.

There are several diminutive forms in the Russian language, like in Spanish.

Yes, the first of diminutive for mouse is мышка (small mouse), but there are possibly some other forms with gradually progressing grades of diminutive (but I think they are much rarely used for mouse itself), for example - мышенька (very small mouse) and мышечка (also very small mouse, rarely used but possible).

  • Oh, yes!! There are a lot of forms in Russian!! Jul 6, 2019 at 10:22
