Say you're stranded on an island with a group of people and you divide your limited food supply. The portion you each receive is your share, also called your allotment. An allotment is a designated amount of money that is automatically distributed for you, from your pay. You can have allotments sent to bank accounts, insurance companies and more
"Allot" can mean a lot of different things, depending on the context. It can be a verb, meaning to distribute or give out (usually resources or time), or a noun meaning a portion or share.
In the context of time management, allotting time for certain activities can help you stay on track and be more productive. For example, you might allot 30 minutes for checking email in the morning, and 60 minutes for working on a project. This can help you to use your time more efficiently.
Conclusion
So, when you allot something, you're setting it aside or distributing it for a specific purpose. Allot can be a helpful tool when you're trying to budget your time or resources.
