Sense: verb/1
These three forms of the verb 'be' differ by tense and subject. 'Is' is present tense and works with singular third-person subjects ('She is a student'). 'Was' is past tense and also takes singular subjects ('He was tired'), but describes a finished situation. 'Were' is the past-tense form for plural subjects ('They were at the park') and for the second-person singular ('You were right'). Many learners confuse 'was' and 'were' by number — remember: 'was' goes with one person or thing; 'were' goes with more than one. A common test: if you would use 'is' in the present, use 'was' in the past; if you would use 'are', use 'were'.

Etymology
The word 'was' comes from Old English 'wæs', which was the first and third person singular past tense form of 'wesan' (meaning 'to be'). This traces back to Proto-Germanic '*was', from the root '*wesaną', and ultimately to the Proto-Indo-European root '*h₂wes-', meaning 'to stay, reside, or spend the night'. The verb 'be' in English is unusual because it combines forms from several different ancient roots.
