Tags the clause before it as a supposition; the consequence follows, often with 就.
字源 FORM what the parts do
話 is words (言); its right side wears the shape of 舌, but the sound rides on a borrowed 𠯑, the donor behind 活 and 括. 的 pins those words onto the clause in front. The whole clause then stands as something put into words and floated, never as something settled.
故事 STORY a scene to remember it by
Someone floats a line aloud, and the room moves on it as if it were true.

框 · Frame
[condition] 的話,(就) [consequence]
觸 · Trigger
Float a what-if and say what would follow.
序 · The move
1State the situation you are supposing, as a full clause.Is this the IF, not the result?
2Close that clause with 的話 and a comma.Does 的話 sit at the END of the supposition, never the consequence?
3Give the consequence, usually opened with 就.Would dropping 的話 still leave a sentence? Then it is a true tag, not load-bearing meaning.
