Make the sisters roll off your tongue.
Some phrases are a pleasure to say. It isn't magic: they alternate consonants and vowels, lean on the most sonorous sounds a mouth can make — l, r, m, n — and keep the tongue from jumping between the lips and the back of the throat. Every rollable here means the same thing in all six sisters and was built to flow in each. Pick one, look at its sound map, then train it the way speech-language pathologists train long utterances: from the end backwards.
[la ˈluna ˈpjɛna ilˈlumina la laˈɡuna]
The full moon lights up the lagoon.

Share of syllables that end in a vowel — CV-CV is the mouth's easiest rhythm.
How resonant the consonants are: l, r, m, n and glides keep the voice flowing; p, t, k stop it.
How little the tongue travels between consonants, from the lips back to the throat.
How rarely consonants pile up three in a row.
How rarely the voice switches on and off inside a consonant cluster.
Why it flows
Almost every syllable is a liquid or nasal plus a vowel — the most sonorous sounds a mouth makes — so the phrase glides without a single hard stop. Catalan turns the l- of lluna and llacuna into palatal ʎ, and Romanian needs no article word at all: luna and laguna carry it at the end.
Backward chaining
Say the end first, then add one word at a time in front of it. Every attempt finishes on the part you already own — the technique speech therapists use for long phrases.
