evening
The crew spent the evening evening out the gravel drive.
The first 'evening' is the noun for the close of the day, and most speakers say it in two syllables — /ˈiːvnɪŋ/ — because the v runs straight into the n with no vowel between them. The second is the present participle of the verb 'to even', to make level, and it keeps all three syllables — /ˈiːvənɪŋ/ — because the schwa of 'even' survives before the ending. Pressed together with nothing between them, the pair makes the reader unpack a syllable mid-phrase: identical letters, one dropped vowel, and a shift from a time of day to an act of flattening.
Meanings

Word origin
The two words were never relatives and did not sound alike until English blurred them together. The time of day is Old English 'æfnung', from 'æfen' (evening), from Proto-Germanic *ēbanths; the levelling verb is Old English 'efen' (level, equal), from Proto-Germanic *ebnaz. 'Æfen' and 'efen' were distinct words with distinct vowels, but the Middle English vowel shifts drove both spellings to 'even', and the two senses have shared one set of letters ever since.
Fun fact
The noun has been shedding syllables for a thousand years. Old English 'æfen' became Middle English 'even', a standalone noun for evening that survives in 'Christmas Eve' — the final -n was mistaken for an inflectional ending and dropped, leaving 'eve'. Poets clipped it further to 'e'en'. So when modern speakers squeeze /ˈiːvənɪŋ/ down to /ˈiːvnɪŋ/, they are only continuing a habit the word has had since the Anglo-Saxons — and it is exactly that habit that splits the spelling in two.
