Some common ones I've discovered:
"stris" (like in nostris) --- not "nos-tris"
"gno" (like in agno) --- not "ag-no"
"cto" (like in sancto) --- not "sanc-to"
"mnes" (like in omnes) --- not "om-nes"
"sic-ut" --- not "si-cut"
de-dí-sti --- not de-dís-ti
re-ctae --- not rec-tae
"ex-ér-ci-tus" --- not "e-xer-ci-tus"
I guess I should (technically) start another post to do so...
I find this very hard to set (in Psalmody) in a satisfying way.
Perhaps it would be fun to find the antiphons distinguished by the presence of words that appear only once in the repertoire.
