Provide at least 5 examples of non-esoteric words with the same letter appearing 3 times in sequence.

Only non-proper words of 6 or more letters qualify.

The word illlit is ill-lit with the hyphen dropped. Though rare,
the dropping of the hyphen is found occasionally in written works,
and can be likened to the removal of diacritics. In some older words where presently a hyphen is usually employed, an adjective formed from the combination of two or more words would be combined, but separated by an apostrophe. Like the hyphen, it too can be found occasionally dropped.

The following are several words where a dropped hyphen (or apostrophe)  can (and occassionally does) present a word with the same letter appearing three times in sequence:

ball-less, bell'libone, bull-like, burgess-ship, cliff-face, countess-ship, cross-selling, cross-shaped, cross-stitch, duchess-ship, free-er, free-est, frill-less, full-length, gill-less, goddess-ship,  governess-ship, headmistress-ship, hill-like, hostess-ship, ill-looking, laparohysterosalpingo-oophorectory, miss-stay, mistress-ship, off-form, pall-like, press-stud, salpingo-oophorectomy, shell-less, shell-like, skill-less, small-leaved, still-life, wall-less, will-less, and will-lessness.

Several interjections, and onomatopoeia (nouns and verbs), are also noted to allow a letter or letters to appear multiple times in sequence. The presence of of the multiple letters in often due to elongation of the vowel or vowel-like sound. The following elongated English words of six or more letters (many that are presented in various elongated lengths) that can be found in the English Wiktionary are:

aaaaah, ahhhhh, aaahing, brrrrr, hmmmmm, mmmmmm, looooove, ooohing, ooohed, pleeease, sooooo, verrry, and zzzing.
