Abandon and retain are opposites. To abandon something is to leave it for good — to let it go and walk away, often leaving it helpless (abandon a post, a plan). To retain something is to keep it deliberately, holding on against the chance of losing it (retain heat, retain staff). One drops the thing to its fate; the other grips it so it cannot slip away.
These two pull opposite ways on whether you hold on. Abandon, from Old French abandoner ('to give up to fate'), lets the thing go — you walk off and it is left, untended. Retain, from Latin retinēre ('to hold back'), is the deliberate opposite: a grip kept on something that would otherwise slip away. Where abandon loosens the hand entirely, retain tightens it. Abandon is release; retain is a held grip.
abandon
To abandon is to walk away and not come back — to give up a thing, a place, or a person entirely, leaving it to its fate. You abandon a sinking ship, an old plan, a search. The word carries finality and often a trace of failure or desertion: what is abandoned is left behind, untended, alone. There is a second, almost opposite sense in the noun phrase 'with abandon', meaning with complete freedom from restraint — but the verb is about letting go for good.
retain
To retain something is to keep it on purpose, holding on against the pull of loss. It comes from Latin retinēre — re-, 'back', plus tenēre, 'to hold' — so a grip is built into the word: you retain heat, moisture, staff, a lawyer, the right to decide. Where keep can be effortless and everyday, retain is deliberate and often formal, used when a thing could slip away if you loosened your hold. To stop retaining is to lose it, or to relinquish it on purpose.

They are opposites — the grip releases or holds. Abandon is the leash slipping from an open hand: the thing let go and left to its fate (abandon ship, abandon the post). Retain is the flask holding its heat as the cold presses in: a deliberate grip on something that might otherwise slip away (retain heat, retain staff). If you let it go for good, you abandon it; if you hold on against the risk of loss, you retain it.

They are opposites, so they don't swap: a soil that abandons water dries out, while a soil that retains water stays moist. Retain adds the sense of holding against loss — exactly what abandon refuses to do.
