This is O' Nolan's book, which sums up all his earlier publications on the subject. I have faithfully re-typeset the book from my fair copy, and with feedback, and help from too many to count, I have made minor adjustments, as listed on the front fly. Again, my effort has been to reflect as far as possible the original layout, and to support the usage of seanchló, though the newer font is here favoured because the archaic fonts with long 's' and long 'r' are easily confused with each other, and also with 'f'. The newer font avoids this fault, which brought seanchló into disregard.

This volume, one of the few devoted to Celtic syntax, makes an important contribution to the description of Celtic, focusing on the ordering of major constituents, pronouns, inflection, compounding, and iode-switching. The articles also address current issues in linguistic theory so that Celticists and theoretical linguists alike find this book valuable.
