Distinguish doing something together from having the same kind or content, including the form of 同じ before nouns.
料金, 値段, and 費用: charges, prices, and overall costs
Distinguish a service charge, an item's price, and the costs of an activity, checking what a claim of no charge covers.

Compare an errand or other business with a commitment made to someone, recognizing that being unavailable does not specify the commitment.

Distinguish employment, performing a role, and making an effort with the shared reading つとめる, comparing に for an employer with を for a role.

Strongly identify a result's cause or something's true nature. Distinguish this from suggesting a possibility, and check why a forceful assertion does not replace evidence.

Focus on one cause while regretting a bad outcome. Distinguish this from temporal たばかり and identify the speaker's evaluation of the cause.
ものだから: explaining personal circumstances
Use ものだから to account for an unexpected reason or personal circumstance. Learn its connections and why explaining a cause does not automatically replace an apology.

Read ものだ presenting a general characteristic or behavioral norm rather than a single event. Distinguish the force of advice or prohibition and the recollective たものだ.
たものだ: looking back on things one used to do
Recall past habits or scenes with たものだ. Distinguish experience, a single event, and whether the same habit continues today.

Use ものなら after a potential form for a possibility regarded as difficult to realize. Separate wishes from actual feasibility and from warnings after a volitional form.
ようものなら: consequences if someone were to act
Use ものなら after a volitional form to present a risky hypothesis. Distinguish an attempted action from actual completion and from wishes using a potential form.
ないことはない: admitting a possibility with reservations
Learn a qualified affirmation formed through double negation. Distinguish potential and ordinary negative forms without expanding the meaning into lack of necessity or enthusiastic agreement.

Express intense heat, pain, anticipation, or desire. Distinguish connecting forms, the direction of the feeling, and whether a following action actually occurred.

Give notice of a risk that is not yet certain. Check verb and noun connections, risks involving a negative clause, and the difference between occurrence and possibility.
かねない: an action could lead to an unwelcome result
Despite its negative-looking form, かねない expresses the possibility of something bad happening. Compare かねる and check the scope of conditions and results.
かねる: difficulty judging and a tactful refusal
