“Come into conflict with (4,4,2)” is almost certainly a British-style crossword clue where “(4,4,2)” gives the pattern of the answer: a 4‑letter word, a 4‑letter word, and a 2‑letter word. In other words, you’re looking for a 10‑letter phrase that means “come into conflict with.”

The natural fit is:

LOCK HORNS WITH

  • LOCK (4)
  • HORNS (5)… so this one actually breaks the 4‑4‑2 pattern.

Because of that mismatch, many solvers instead look for a phrase like “CLASH WITH” (5‑4) or “FALL OUT WITH” (4‑3‑4), but these do not match 4‑4‑2 cleanly either.

Given the specific “4 4 2” enumeration you supplied and the clue “come into conflict with,” the intended answer is almost certainly a 10‑letter, three‑word phrase meaning “to oppose or clash,” but the exact 4‑4‑2 breakdown is a bit unusual for the standard options. If this came from a particular puzzle (e.g., Mirror Classic dated 12 Feb 2026), checking that puzzle’s official solution list would confirm the exact entry the setter used.

If you’d like, paste any checked letters you already have (e.g., “_ _ _ _ _ _ _ _ _ _”) and I can help narrow it further.
