The Triphthongs are nice and easy to close with - they are 5 of the diphthongs with the neutral vowel at the end:
EYE followed by uh gives us: IRE as in “fire”
This triphthong can also be shortened to just AH as in o.u.r as in “are country” - the full sound is “our”: “our country”.
OYER as in “employer” is the OY sound followed by the neutral “uh”
OER as in “mower” which is OH plus the neutral vowel “uh”
