I am looking for a single word that can describe something that is continuing to grow. The only term that comes to mind is viral but I am looking for something different.

For an example, an activity that continually spawns other activities.

The smaller tasks continue to grow because of the ______ task.

  • Please give a sample sentence.

I'd suggest hydralike, which is an adjective form of 'hydra'.

A Hydra, according to Greek mythology, is a many-headed beast that has a curious habit of growing two more heads every time you cut one off. (Heracles/Hercules had to defeat one in his second task.)

It has taken on the meaning of:

A complex, multifarious problem or situation that cannot be solved easily and rapidly


And is apt for describing problems that get increasingly complex.


vigorous adjective

Merriam Webster:

2 : possessing vigor : full of physical or mental strength or active force : STRONG a vigorous youth a vigorous plant


fecund - producing many good new things

Typically used in the context of fertility or intellectual creativity, per vocabulary.com

I'm thinking it's a close synonym to virulent with more neutral connotation.


Spawn. verb, meaning ‘to produce young ones’

Means ‘continues to birth more young ones, similar to itself’

Consider being poetic and liken it to yoghurt or yeast, baby fish, or... mushrooms.

Each mushroom spawns another fairy ring. Which then spawns others.

The tasks continue to spawn.

INTRANSITIVE/TRANSITIVE] to produce spawn Synonyms and related words Give birth to a young animal:albumen, calve, foal... Explore Thesaurus 2 [TRANSITIVE] if one thing spawns something else, it creates it The book was a fantastic success, spawning a hit TV series. Synonyms and related words To make something start to exist or happen:bring about, trigger, form...


The tasks continue to spawn further tasks.


Generative seems to be appropriate here. Something which is generative has the power to reproduce, or produce new things, which I think is what you are looking for.

According to Cambridge Dictionary: Adjective able to produce or create something

Example use in phrase: the generative power of the mind

and the Merriam-Webster definition: having the power or function of generating, originating, producing, or reproducing


I would say SWELLING.

According to Oxford Living Dictionary




Becoming greater in intensity, number, amount, or volume.

‘the swelling ranks of Irish singer-songwriters’
