As subjects of a verb, pronouns may be included in the suffix that identifies a tense, or may appear in the same position as nouns:
Tuigim. I understand.
Thuig mé. I understood.
Feicimid Peige. We see Peige.
Feiceann muid Peige. We see Peige.
Bhíodar anseo. They were here.
Bhí siad anseo. They were here.
Most pronouns have the same form whether subject or object, but a few are different. Compare:
Tá sí anseo. She is here.
Tuigim í. I understand her.
Tá sé anseo. He is here.
Tuigim é. I understand him.
Tá siad anseo. They are here.
Tuigim iad. I understand them.
Tá tú anseo. You are here.
Tuighim t(h)ú. I understand you. (The difference here, I assume, is the lenition based on gender.)
The third-person pronnouns begin with s when they are used as subjects, but s disappears when they are objects, and tú may be lenited, becoming thú. The other pronouns (mé, sibh, muid, sinn) do not change form.
The full rule is that the forms with s are used when the pronoun:
1. is the subject of the verb
2. immediately follows that verb
e.g. Bhí mise agus eisean ansin. He and I were there.
Is cailín deas í. She is a nice girl.
And then I suddenly realized I was on chapter 22 of 25 and almost done with the Irish book. And I still have no idea what I'm doing! Which is fine, but at some point I really need to institute a practice of, well, practice. Although the semi-frightening thing is I actually mostly understand pronouns at this point.
I'm not even sure I have anything to say. Writing will continue to be attempted, I actually got more written yesterday than I did the day before so, yay? Improvements! And today also looks relatively quieter for incoming at least, so that won't be terrible. Hopefully if I can get a good sized chunk of writing done today I can come home and do all the fiddly little household tasks I haven't caught up yet with tonight. And I have two... three pieces of correspondence to deal with today and hopefully I can remember to do that. Now that I've put it on the list of things to do?
(It turns out I can, while I cannot remember to post this on time oops. On the plus side I've finished shipping, those correspondences, and other junk today. And did Russian. SO.)
Right. I have massive quantities of writing shit to do, so let's get this shit done.
