Note

- 3To keep something within limits; to restrain or confine it so it does not spread.
Officials struggled to contain the spread of the disease.
Strict budgets contained the project's costs throughout the year.
UsageOften of things that spread: contain a fire, an outbreak, costs. With people, contain yourself means stay calm.
Similarcontrol, curb, limit, restrain, check
Note
Restraint replaces enclosure here: what is contained is kept from spreading or breaking out. With people it is most often reflexive ("I can hardly contain myself"), and Shakespeare already writes "we can contain ourselves" in The Taming of the Shrew. Besant's The Ivory Gate plays this meaning against the enclosing sense, saying no cab could contain a young man in such a rage.

Note
The emotional use keeps the Latin picture of holding together: a feeling is treated as something that would spill over if it were not held in. It is a close cousin of the "keep within bounds" meaning, turned inward.
- 5To restrain one's desires, and in particular to abstain from sexual activity and remain chaste.
But if they cannot contain, let them marry.
1611, The Holy Bible, King James VersionNote
Here the restraint has no object: one does not contain anything, one simply contains, holding desire in check. The King James Bible of 1611 puts it bluntly: "But if they cannot contain, let them marry." It is the intransitive offshoot of the "restrain" meaning, and it is obsolete.
