'cot' and 'camp bed' In American English, a cot is a narrow bed for an adult. It is made of canvas fitted over a frame, and you can fold it up. You take it with you when you go camping, or you use it as a spare bed at home. In British English, a bed like this is called a camp bed.
Across is a preposition. It describes the relationship between two persons, places, or things. It is sometimes used with the preposition from. Example: That house is across the street. Cross is most commonly a verb or noun. Crossed is the past tense or past participle of the verb to cross.
For additional protection, a cheque can be crossed, which restricts the use of the cheque so that the funds must be paid into a bank account. The format and wording varies from country to country, but generally two parallel lines may be placed either vertically across the cheque or in the top left hand corner.
