"Geoin mhín na mban agus na bhfear le balla ag cumascadh le searbhán géar gúnaí nuacheannaithe, le gáirí ar mhó den ghangaid ná den ghile iad, agus le culghaire tomhaiste an damhsa ar na cláir bhealaithe."

Rinne mé google le haghaidh "culgaire" agus fuair i dtéacsanna sean ghaeilge é.

Mar shampla anseo :
http://vassun.vassar.edu/~sttaylor/Cooley/Ferdiad.html

", & nuallgrith na roth & culgaire in charpait & basschaire na n-ech & trommchoblach in churad"

Tugtar aistriú air mar
"and the whirr of wheels, and the creaking of the chariot, and the trampling of horses' hoofs, and the deep voice of the hero"

Glacaim leis mar sin gurbh torann an damhsa ar na cláir atá i gceist.

Feachfad i Dineen chun é a chinntiú. Ach dúirt an Cadhnach nach raibh aon leisce air focal a thógaint ón tseanlitríocht más amhlaidh gurbh fhearr an focal sin.

Shíl mé go mb'fhéidir "cúl" + "gaire" é.

"culghaire tomhaiste" - measured (backward) proximity?

They didn't want to get too close to each other?

Táim cinnte gurbh fuaim atá i gceist.

Tá an méid seo ag Dineen faoin gceannfhocail ghaire: in early compounds; sound, call, voice, noise; cul-ghaire clatter of chariots.

Déarfainn ansin:

..mb'fhéidir gur "cúl"...

Actually, I would've used "gurbh fhéidir"... I actually quite like how there's such variation in Irish. If you take a look in the Irish Only part of the board, you'll see a post by a fella talking about how they speak English in the shop in the Gaeltacht. To some it may look like there's loads of grammatical and spelling errors, but in reality it's just another construction!

Is dócha go bhfuil an ceart agat, a Aonghuis. Go raibh maith agat arís.
