字源 FORM what the parts do
Two brackets close round one party. 對 opens it: a hand (寸) raises the notched tablet (丵) and turns to face the one across. 來說 closes it: 來 (the wheat graph, on loan for "come") and 說 (words 言, 兌 on loan for sound) read as "comes round to be said." The party whose side you take sits between.
故事 STORY a scene to remember it by
A chair sits empty at one place round the table; someone crosses over and takes it. From that seat the same matter weighs its own way, and that weight is what comes out.

框 · Frame
對 [perspective-holder] 來說，[comment from that standpoint]
觸 · Trigger
You want to seat a judgment in one party's point of view — say how a thing looks or matters for them, not aim an action at them.
序 · The move
1Open with 對 and name the party whose vantage you take.Is the slot after 對 the one whose viewpoint frames the comment, not a target the verb acts on?
2Close the bracket with 來說 and a pause, then state the comment.Could the comment stand alone, with 對…來說 only seating the viewpoint?
3Read it back from the picture.Does it report how the thing weighs from their seat (success), rather than send an action at the person (failure)?
例 · Examples
1對幼兒young child來說，遊戲就是is precisely他生活中最重要的事the most important thing。
For a small child, play is the most important thing in their life.
Directional 對 aims an action at the person faced (對我笑 = smile at me). 對…來說 seats a judgment in their viewpoint and lands no action on them (對我來說 = from where I stand). Action-recipient against viewpoint-seat.
至於 switches the topic to a new item (至於錢，再說 = as for the money, later). 對…來說 holds one party's standpoint and reports how things weigh from it. Topic-switch against standpoint-anchor.
✗ 對我來說笑 → ✓ 對我笑 (an action aimed at a person drops 來說; 對…來說 frames a viewpoint, not a target)
✗ 來說對學生這很難 → ✓ 對學生來說，這很難 (對 opens, the party sits between, 來說 closes — the brackets do not swap)
✗ 對他來說我很重要 read as "I matter to him" → ✓ leave the affected-party sense to bare 對 (他對我很重要); 對…來說 reports how it looks from his seat, not whom it affects
English 'for X' covers both 'X is affected' and 'from X's point of view'. 對…來說 is only the second; the affected-party 'for' often wants bare 對 or 給 instead.
