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