Question

Walk carefully lest you ______ fall (shall)​

Answer 1

walk carefully least you (shall not) fall

Answer 2

The correct sentence will be - "Walk carefully lest you shall fall".

• In the English language, we often use a special type of word to join two words, phrases or sentences. These words are called Conjunctions.
• There are mainly three types of Conjunctions, Coordinating conjunctions, Correlative conjunctions, and Subordinating conjunctions.
• The word "lest" is a subordinating conjunction. This conjunction is used to alert about an unfortunate or negative event. The word "lest" is followed by a sentence containing "should".
• Here in the given sentence, the speaker is trying to alert about someone's falling. So the sentence will be "Walk carefully lest you shall fall".
