Word of the day

I have learned one word today.

Word: Incubate
Verb: meaning

1. To sit on (eggs) to provide heat, so as to promote embryonic development and the hatching of young;
2. To maintain (eggs, organisms, or living tissue) at optimal environmental conditions for growth and development.
3. To maintain (a chemical or biochemical system) under specific conditions in order to promote a particular reaction.
4. To form or consider slowly and protectively, as if hatching: incubated the idea for a while, then announced it.

Where i can use:
I often “incubate” a particular concept for a few days before concluding anything.
