This is impossible for a language

[Mauro]

In Spanish and Portuguese, 'antes' is a very common word that means 'before'.  But it is also a suffix like English '-ents' and '-ants', so there are many hundreds of words that end with '-antes', like 'estudiantes', 'cantantes', 'passantes', ...

In Italian 'vino' of course is a very common word, but it is also the ending of all nouns and adjectives that end in '-vo' when inflected in the diminutive: 'bravo' -> 'bravino', and also of all verbs that end in '-vare' when inflected in the subjunctive 3rd plural: 'provare' -> 'provino', 'trovare' -> 'trovino'...

In Italian I would add 'mente'. It means both 'mind' and 'he/she lies' and is also an extremely common adverbial suffix, similar to English '-ly'. Abitualmente (usually), attualmente (currently), banalmente (trivially), casualmente (randomly), dannosamente (harmfully), estremamente (extremely)... thousands of words I guess, surely (sicuramente) many hundreds (*).

(*) I then asked Google (translated and shortened): many thousands attested in the dictionaries, but it's impossible to give an exact number because the suffix is extremely productive and new words in -mente are continually evolving.

And I guess this holds for most languages.
