Crossword Clue: Butter substitute
Here's the answer to the Butter substitute crossword clue, with an explanation and where it has appeared.
Definition & answer: OLEO
The answer to "Butter substitute" is OLEO. Oleo is a 4-letter word made up of 3 vowels and 1 consonant, beginning with O and ending with O. In a crossword grid it occupies a 4-square slot, and each of its letters also forms part of a word crossing it — so even if the clue stumps you, the crossing entries will usually hand you enough letters to fill it in.
Origin & meaning
Oleo is an old shortening of oleomargarine, the vegetable-based butter alternative. Its O-L-E-O palindrome-like shape makes it one of the most useful four-letter grid entries.
Common usage
Oleo turns up frequently in crosswords precisely because of that letter mix. Short, vowel-friendly words like OLEO are a constructor's best friend: they interlock cleanly with longer entries and help a grid come together without awkward letter clashes. When you see a 4-letter slot and already have a crossing letter or two, OLEO is often quick to confirm — especially once the O or O is in place.
Crossword trivia
Because it is only 4 letters long, OLEO appears far more often in daily mini and themed puzzles than longer, more obscure words. Regular solvers come to recognize it on sight, and it is exactly the kind of entry worth committing to memory: the more common short words you know cold, the faster your solve times become.
Stuck on this clue?
If "Butter substitute" has you stuck, don't force it — jump to the clues crossing this slot instead. Filling in even one or two intersecting letters usually makes OLEO obvious. That crossing-first approach is the single most useful habit for improving at crosswords, and it works on everything from the quick daily Mini to a full Sunday grid.
