Here are some ways it can be used:
* My teaghlach (My family)
* An teaghlach mór (The big family, often referring to extended family)
* Bean na tí agus an teaghlach (The housewife and the family)
You might also see the word "teaghlaigh" which is the genitive case of "teaghlach" and means "of the family".
So, if you're ever in Ireland and hear someone mention "teaghlach," it means they're talking about their family!
