Yesterday I learnt that to Polish speakers Czech can sound cute, as quite a few Czech words sound like diminutives in Polish. For example cat is kot in Polish and kočka in Czech. Polish diminutives of kot are kotka and kociątko. A Czech diminutive of kočka is koťátko.
What do closely related languages or varieties of your language sound like to you?
Do any of them sound cute like Czech to Polish speakers?
How does Polish sound to Czech speakers?
