難免grammar point · tier 1 · inevitability 難免 (hard to avoid → bound to, can't help but)
Marks an outcome as hard to avoid given the situation: the following state or reaction is bound to come, though it is never anyone's fault.
字源 FORM what the parts do
難 pairs a bird (隹) with 堇 lent for sound; the 'difficult, hard-to' sense is borrowed onto that sound. 免 is the crouching body that twists free and slips out from under a reaching hand — to escape, to avoid. 難 set before 免 weights the escape: the dodge is there, but hard to take. What follows is the outcome that mostly comes anyway.
故事 STORY a scene to remember it by
The body crouches to slip free, but the gap is narrow and the hand is fast, and it rarely clears.
字源記憶法自撰
框 · Frame
[situation], 難免 [(會) verb / state that follows]
觸 · Trigger
Given the setup, you want to say the outcome is hard to dodge — it is bound to turn up, and no one is at fault for it.
序 · The move
1Set the situation that makes the outcome hard to escape in the front clause, often after a concession (即使 / 雖然).Does the outcome follow from the setup on its own, with no one choosing it?
2Place 難免 before the reaction or state that comes anyway; 會 often follows it.Is what follows a natural consequence (a feeling, a flaw, a mishap), not an action someone is compelled to perform?
3Read it as 'hard to avoid' — the escape exists but rarely succeeds.If the sentence needs a person with no choice but to act, switch to 不得不; if it needs flat certainty that the thing simply comes, 不免 reads a shade stronger.
例 · Examples
1即使even if, even though是新車，難免hard to avoid → bound to, can't help but也會有些小毛病fault, defect, glitch。
Even a brand-new car is bound to have a few small faults.
難免 and 不免 both mark something as hard to avoid and often swap. 難免 weighs the escape and finds it hard (a slip is still imaginable); 不免 finds the escape already failed (it comes). 難免 = hard to escape; 不免 = not escaped, a shade more certain and more written.
不得不 forces an agent to act — they have no choice but to do X (不得不轉學 = has no choice but to transfer schools). 難免 makes an outcome arrive on its own — no one acts, the result is just hard to dodge (難免擔心 = can't help worrying). 不得不 = compelled to do; 難免 = bound to happen.
✗ 我難免去學校。 → ✓ 我不得不去學校。 (a person forced to take an action needs 不得不; 難免 marks a consequence that is hard to escape, not a chosen act)
✗ 新車難免有小毛病嗎？ → ✓ 新車難免會有小毛病。 (難免 states a hard-to-avoid outcome flatly; it does not head a question or a command)
✗ 第一次上台，他難免了緊張。 → ✓ 第一次上台，他難免緊張。 (難免 sits directly before the verb or state of the reaction; do not split it or hang 了 on it)
English reaches for 'have to' or 'must' for both compulsion and inevitability; 難免 covers only the second — the result that is hard to escape — and never the person who is made to act. English 'inevitably' also reads as flat certainty, but 難免 keeps the trace of 'hard to' that leaves the slip just imaginable.
