Yes, "frail" does not have a suffix. It is a standalone word.
The word "frail" is an adjective that describes someone or something that is delicate or weak.
"Frail" comes from the Latin word fragilis, "breakable", via Old French frele. Fragilis in turn comes from the verb frangere, "to break". Believe it or not, frangere and "break" (and thus "frail" and "breakable") are related: they ultimately both come from the Proto-Indo-European root bhreg.

But that isn't a sentence, it is a sentence fragment. Let's say you want to use that fragment in a sentence. You might say something like, My neighbor is a thin, frail, elderly-appearing 65-year-old lady. As an editor I would also point out that if you have already noted that this woman is thin and frail and 65 years old, it is really superfluous to also state that her appearance is elderly. I would omit that phrase.
