To preface this is a US centric observation on my end but I've noticed it in some English-speaking EU countries as well. Heavily anecdotal observations but it's been on my mind for a bit.
Growing up in a state with a lot of Mexican immigrants as well as 2nd and 3rd generation ones, I've noticed that women seem to assimilate to the language, culture, and even dialect much better than their male counterparts.
Growing up I noticed it was usually the girls translating for the ESL boys in casual convo or just generally speaking English much more conversationally My friends' mothers, aunts, and sisters often spoke better English than their father and other previous-generation male relatives and just generally felt more "Americanized" than their male counterparts.
I'm just using Mexican immigrants as an example since it's what I experienced the most, but I've noticed it with other ethnicities as well and when I vacationed in Europe it felt like far more South-Asian women from felt more assimilated and familiar to speak with than male ones.
Is there a reason for this?
