てから

てから welds the two events tightly (often a precondition) and alone carries the durative "since" reading (来きてから三年さんねんになる). たあとで merely states the order and tolerates any gap.

てから names both steps in one sentence (洗あらってから切きる). まず just names the first step, then moves on (まず手てを洗あらう).

てから makes the first event a precondition inside one sentence (お金かねを入いれてから、ボタンを押おします). それから just claims order, and heads a spoken list of steps.

Bare て leaves the gap unmeasured, and tolerates three or four actions. てから locks in exactly two, making the first the precondition for the second.

てから just orders two events, nothing more (シャワーを浴あびてから寝ねる). て初はじめて needs a realization caused only by the て-part (使つかってはじめて分わかった).

てから just marks a starting point, fitting any span or event after it. て以来いらい also claims the resulting state has run unbroken to now.

てから only orders the two events, leaving what follows free. てからでないと makes the first a precondition and forces a negative after it (×お返事へんじできます).

てから just orders two actions strictly, with no comment on effort (歯はを磨みがいてから寝ねる). ついでに instead makes the second action free-riding on a trip already being made (歯医者はいしゃに行いくついでに、本屋ほんやにも寄よった).

てから just orders two actions, with no weight of its own. 上うえで treats the first action as a considered step (相談そうだんした上うえで決きめる).

てから orders two events (飲のんでから帰かえる). から after a plain form gives a reason instead (飲のんだから帰かえる).

これから counts from this moment and stands on its own. 〜てから needs a verb in front and counts from that act (食たべてから).
