How to spell third

hear itthird/θɜrd/adjectiveStarter

What it means: Coming next after the second in position.

In a sentence: I ate my third cookie today.

The part people get wrong

Often misspelled as thrid or therd.

Same family: three, thirdly, thirds, third-place, third-party. If you can spell one, the shared part carries to the others.

Where it comes from: “Third” comes from Old English “þridda,” which originally meant “the third one.” Over time, the ‘r’ and vowel sounds switched places (a process called metathesis), turning earlier forms like “thrid” into the modern “third.”
