Touchdown vs. Touch Down
“Touchdown” and “touch down” differ mainly by grammatical function. Cambridge records the closed form as a countable noun for landing and sports senses and the two-word form as a phrasal verb, including aircraft landing and rugby uses.
Use “touchdown” as a noun and “touch down” as the phrasal verb. A plane can “touch down”; its landing is a “touchdown.”

Quick tests
Noun-or-verb test
Is the word naming an event or score rather than functioning as the verb?
If yes: Use the noun “touchdown.”
If no: For the phrasal verb, write “touch down.”
Caveat: The spelling distinction follows grammatical function; do not collapse the noun and verb into one form.

Further guidance
Core difference
Use “touchdown” as the noun for a landing or a scoring event; use “touch down” as the verb for landing or, in rugby, grounding the ball.
Fast Test
If the expression can be inflected as “touched down” or “touching down,” use the two-word verb.
Usage Boundary
Keep the grammatical role clear: the closed noun and spaced phrasal verb can occur in closely related landing or sports contexts without being interchangeable spellings.
