.or maybe not but ...
I wanted to find out how I would say
Mediterranean Nights

so dictionary says
Mediterranean = Meánmhuiri ( adj)
and night = Tráthnóna

So using what I have been picking up here and elsewhere mediterranean nights should be

Tráthónai Mheánmhuiri

or did I mess up in my guesswork ,, does the adjective lenite ? should I have put 'na ' between them to signify 'of the' and used the noun form meanmhuir ?????

any help appreciated

The Mediterranean Sea = An Mhéanmhuir

méan = middle
muir = sea

Here's you first problem, do chéad fhadhb. There's no Gaeilge, AFAIK, for "The Mediterranean", or an adjective such as "Mediterranean". Concordantly, you'll have to associate it with "The Mediterranean Sea".

If you want the definite article, ie. "The Mediterranean Sea's Nights":

Oícheanta na Méanmhuire

If you're looking for the indefinite article, ie. "Mediterranean Sea Nights":

Oícheanta den Mhéanmhuir


The problem with "Oícheanta Méanmhuire" is that "Méanmhuir" is indefinite, but ofcourse you want it to be definite, there's only one Mediterranean Sea after all.

The gurus will put you right. But you should note the plural form of 'tráthnóna' is 'tráthnónta'. Surprisingly, Mediterranean is classified as an adjective only in Ó Dónaill. (The Mediterranean?) I would attempt = Tráthnónta Meánmhuirí. = Chaith mé na tráthnónta Meánmhuirí le mo chara.

In English, words such as Mediterranean, American, Mexican, etc are referred to as "proper adjectives," and to my understanding, the context determines whether the word is a noun or an adjective.

He was born in Mexico. (noun)

He is a Mexican. (noun)

He wears a Mexican sombrero. (adj.)

I look at them as being two different words altogether. For instance, look up "morning" in the dictionary and you'll find two completely different meanings. Similarly, "mexican" is an adjective. "mexican" is a noun.

Your dictionary has misled you!
Night = Oíche

I'd suggest
Oícheanta Méanmhara

mara is the genitive of muir.

Oícheanta Meánmhara

I keep misplacing fadas. I understand the board upgrade will allow me to fix typos when I notice them - that will be nice.
