   ここで明確めいかくにしなければならない点てんは、スポーツにおいてアマチュアとプロフェッショナルの境界線きょうかいせんが消失しょうしつしつつあるということだ。↗

   The point we must clarify here is that the lines between amateur and professional in sport are beginning to disappear.

• Synonym消滅しょうめつNeutralComplete extinction or ceasing to be valid, as in 「権利の消滅」「種の消滅」. Stresses being gone for good — more final than 消失.
• Synonym消えるきえるNeutralThe everyday verb for disappearing or going out (lights, feelings). In speech this, not 消失, is the default; 消失 is the Sino-Japanese written term.
• SynonymなくなるNeutralColloquial verb for being gone, lost or used up, concrete or abstract, as in 「自信が無くなる」. 消失 is the more written-flavoured choice.
• Synonym消え入るきえいるNeutralVerb for a voice or sound fading little by little until gone; also feeling faint with shame or grief. Stresses the gradual fade 消失 doesn't.
• Synonym消え失せるきえうせるNeutralVerb: vanish without a trace. Also used to tell someone off, as in 「消え失せろ」. Colloquial with a strong tone, unlike the neutral written 消失.
• Synonym掻き消えるかききえるNeutralVerb for sounds, light or smells suddenly dying out and leaving no trace — an instant, traceless vanishing that 消失 does not specify.
• Synonym消散しょうさんWrittenWritten word for smoke, smells and the like dispersing into the air. Stresses spreading and dissipating rather than simply vanishing.
• Related吹き飛ぶふきとぶNeutralVerb: blown away by the wind, or figuratively swept away all at once, as when worries vanish. Stresses a sudden, one-shot dispersal.
• Related吹っ飛ぶふっとぶCasualColloquial counterpart of 吹き飛ぶ: blown away, or vanishing in a flash. Stronger, punchier tone than either it or 消失.
• Related去るさるNeutralVerb for leaving or passing (of time). Stresses departure — the thing moves away but need not vanish, unlike 消失.
• Related消去しょうきょNeutralDeliberate erasure or deletion by someone, as in 「データ消去」. Use when the disappearance is man-made, not spontaneous.
• Related消し去るけしさるNeutralTransitive verb for wiping something out completely, as in 「記憶を消し去る」. Stresses deliberate, total erasure by an agent.
• Related失せるうせるCasualColloquial verb for disappearing or clearing off; the imperative 「失せろ」 is blunt and rude. Rougher than 消失.
• Related失せ去るうせさるWrittenWritten verb for vanishing from sight; rarely used and literary in feel, so it sounds bookish next to the plain written 消失.
• Related没するぼっするWrittenWritten verb for sinking (ships, the sun) or passing away; also 'vanish'. Stresses going under or dying rather than mere disappearance.
• Related消除しょうじょWrittenWritten word for removal or deletion; as a verb it can also mean vanishing on its own. Rare, and mostly about eliminating something.
• Antonym出現しゅつげんNeutralAntonym: appearing or coming into view — the direct opposite of things vanishing.
• Antonym発生はっせいNeutralAntonym: occurring or arising (events, problems, power). Opposite of 消失 in the sense of something coming into being.

For something vanishing, 「消失」 is the written, formal choice — 「データが消失する」「権利の消失」. In everyday speech use 「消える」. Say 「消滅」 for complete extinction, 「消去」 for deliberate deletion, 「無くなる」 for things lost or used up. Antonyms: 「出現」「発生」.
