I've been reading よつばと! and I'm on a chapter where Fuuka has a crush on a guy. She says this:
手ぇつないで歩いてたの
I assume the small e is just for emphasis/extension and it doesn't seem to serve a grammatical function (though I'd like to know that for sure), but that's not what poses a problem for me. I have no idea what つないで means. I can't find a definition for it, nor can I for つなぐ, つる, or つある, all of which it is possible inflections of. Can somebody define this for me?
