Here are some palindromes in English:
redivider (one who divides more than once)
Finnish holds the world record for the longest palindrome:
saippuakivikauppias (literally, "soap-stone-seller", or in other words, a lye-dealer)
reconocer (the verb, "to recognize")
rattar ("steering wheels"; also slang for "breasts")
onorarono ("to give honor")
ressasser ("to repeat the same thing over and over")
I was recently informed about what is supposedly the longest palindrome in German, namely, reliefpfeiler ("pilaster" in English).

The unfamiliar word uricosuric (increased excretion of uric acid in the urine) is also a 5/3-power.
The word brekekekex, devised by Aristophanes to represent frogs croaking, contains a 7/2-power.
The words alfalfa and entente, mentioned previously, are 7/3-powers. The words lophophore and Mississippi contain 7/3-powers.

English has the Abelian squares
as well as the less familiar words indenied, notition, vetitive, horseshoer, and meteorometer.
French, however, is positively overflowing with abelian squares. To
list just a few:
resseres (as in "tu resserres", "you make tighter")
entaillaient (as in "ils entaillaient", "they make a deep cut")
entassassent (as in "qu'ils entassassent", subjunctive of "entasser", "to put in the same place")
entrainerait (conditional of verb "entrainer", "to train" (as for an athletic event))
ressassera (from "ressasser", to repeat the same thing over and over)
retaillerait (conditional of verb "retailler", "to retailor")
taillait (imperfect of "tailler", "to tailor") tarirait (conditional of "tarir", "to cease flowing") tenaillaient (imperfect of "tenailler", "to nail down") trairait (from "traire", "to milk a cow")
German has the very nice 14-letter Abelian square interessierten.
Dutch has entten (grafted); gedoogde (tolerated); gieriger (more miserly); intentie (intention); meenemen (to take along); and overvoer (overfeed).
