Doesn't that sentence sound wonderful :)
If leis means "with him," what does "with her," look like?
liom, leat, leis, léi, linn, libh, leo.
Note that le also becomes leis before an and na - (leis an madra, leis na cailíní). That's not the same leis so it never becomes léi.
Ok, I think I understand. Thanks!!!!
