Sense: verb/1
'Contain' suggests that something is physically inside a space or is a component of a larger whole — a box contains tools; a meal contains protein. 'Hold' is more informal and focuses on capacity: a jug holds two litres, but we do not say a meal holds protein. 'Include' is the broadest of the three and works for both physical and abstract sets — 'the price includes tax' — but does not imply physical enclosure. 'Accommodate' is about whether there is enough room for a certain number or amount: 'the hall accommodates 300 guests.' For physical containment, 'contain' and 'hold' overlap, but 'contain' is preferred for listing ingredients, components, or hidden contents. Example: 'The report contains a warning about safety' vs. 'The report includes a warning about safety' — both work, but 'contains' feels more integral to the document's content.

Etymology
'Contain' entered English through Old French 'contenir', from Latin 'continere' — 'com-' (together) plus 'tenere' (to hold). The original sense was 'to hold together', which led to both 'having something inside' and 'keeping within limits'. The emotion-control sense appeared in the late 1500s, and the sports-specific uses developed in the 1900s.
