• Synonym延滞えんたいWrittenWritten word for arrears or something overdue, chiefly payments, as in 「延滞金」; about passing a deadline, not general delay.
• Synonym遅らせるおくらせるNeutralSame meaning as 「遅らす」—to delay, postpone or slow something—but the more commonly used form of the two.

• Related持ち越すもちこすNeutralVerb for carrying an unsettled matter over to a later occasion, as in 「次回に持ち越す」; about deferring items, not about progress slowing.
• Related繰り延べくりのべWrittenWritten noun for the deliberate pushing back of schedules or deadlines; 「遅滞」 is progress being blocked, not an active postponement.
• Related滞りとどこおりWrittenWritten word for stagnation or things not going smoothly; often in the phrase 「滞りなく」, meaning progress is unimpeded.

• Related遷延せんえんWrittenRare written word stressing that something drags on for a long time without resolution; more about prolonged duration than the blockage in 「遅滞」.

• Related延び延びのびのびNeutralDescribes something being put off again and again, as in 「延び延びになる」; the emphasis is on repeated postponement.
• Antonym迅速じんそくWrittenAntonym: swift and prompt action, in written style; the opposite of the dragging, sluggish progress expressed by 「遅滞」.
• Antonym順調じゅんちょうNeutralAntonym: things proceeding smoothly and well; contrasts with 「遅滞」, where progress is held up.

In official documents, for affairs dragging or stalling use 「遅滞」, often as 「遅滞なく」. For everyday delays use 「遅れ」, for transport delays 「遅延」, and for a deliberate change of date 「延期」. Other words cover special cases: 「延滞」 overdue payments, 「持ち越す」 carrying items over, 「もたもた」 dawdling, 「延び延び」 repeated postponement, with 「迅速」 and 「順調」 as opposites for promptness and smooth progress.
