Explanation

'Lest' requires the subjunctive mood, which uses the base form of the verb. The phrase 'lest you fall' means 'so that you don't fall' or 'for fear that you might fall.' The base form 'fall' is grammatically required after 'lest.'

AI explanation

'Lest' introduces a clause expressing something to be avoided and is traditionally followed by the base form of the verb (the subjunctive), as in 'lest you fall.' Forms like 'fallen,' 'was falling,' or 'has fallen' don't fit this grammatical construction after 'lest.'
