Rannaigheacht bheag (ran-á-yah voig)

A traditional Irish quatrain of 7-syllable lines [7/7/7/7] (‘old-school’),
 or 8/6/8/6, ending in 2-syllable words all linked by consonance
(in its old meaning, ‘having the same vowels’),
 with at least two cross-rimes in each couplet
 (can be consonance in first but should be rime in second)
and alliteration in every line, which in the second couplet
 must be between the last two stressed words in each line,
and with the dunedh, of course (ending in the same word, phrase,
 or line it began with).
Poem ExampleRon-a’yach Rhyme

Writing rhyming words, giving
living lines, fit for fighting
biting boredom while living
in style with witty writing.

As with the other Irish forms, a template can show you the syllable count and a bit more, but cannot be definitive as so much variation is possible while meeting the formal  requirements.
In the example below some words not hi-lighted could have been as serving one or more rules.

Rionnaird tri-nard (RUN-ard tree-nard)

Rionnaird tri-nard (RUN-ard tree-nard), traditional Irish quatrain
form with 6-syllable lines ending in 2-syllable words,
L2 and L4 riming and L3 in consonance thereto (meaning in this case,
I gather, vowel-agreement rather than consonant-agreement,
having at one time meant the same thing as assonance),
alliteration in every line (ideally between the end-word and the
preceding stressed word), two cross-rimes in the 2nd couplet,
and the 1st stressed word of L2 alliterating with the last syllable of L1.
 Being Irish, it requires the dunedh, to end where it began
(first word, phrase, or line repeated in closing).
Example Poem
Promise
 
Inviting just by sight,
almost tinsel trapping,
stilletoed toes tripping,
in her sheer hose wrapping.
She’s surely sensuous;
Suggests sex is waiting,
waits while will is wilting.
Still fates are Inviting.

I see here now that I have failed, if indeed every line
is to end in two-syllable words.  Ah well, close.
