as a verb, 'ran' denotes the action of moving swiftly on foot, managing or operating something, or a variety of other actions or states that 'run' can describe, but in the past.

The river ran dry during the summer.
'Ran' is irregular, so it doesn't follow the typical '-ed' pattern for regular past tense verbs in English.
It's essential to differentiate between the base form 'run,' the past tense 'ran,' and the past participle 'run' (used with have, as in 'have run').
'Ran' can also be used metaphorically, as in 'thoughts ran through my mind.'
