📌 Core Rules Reference

1. Might as well / May as well (+ base verb) Negative: might as well not

When you have no better choices, this phrase suggests doing something anyway. Doing it will not hurt or cost you anything. It is a soft suggestion and never a prediction.

🔹 "The casino has closed for the night, so we might as well walk home."

🔹 "With such terrible odds, you might as well not buy a ticket."

2. May well (+ base verb) Negative: may well not

This expression shows that an action is quite likely to happen. It is stronger than may, but less certain than 'be bound to'. The word 'not' comes right after 'well'.

🔹 "The jackpot may well go unclaimed again this week."

🔹 "The bookmaker may well not accept such a huge wager."

3. Would sooner / Would rather / Had best Negative: had best not

Use 'would sooner' to show preference over another choice. Use a past verb form when choosing for someone else. Use 'had best' to give strong advice with warning.

🔹 "He would sooner give his money to a charity than buy a lottery ticket."

🔹 "You had best call the gambling helpline before this becomes a serious addiction."

4. Can't help / Cannot but Never use to-verb

Use these expressions when you cannot stop a feeling or action. Follow 'can't help' with an -ing verb and never place 'to' after it. 'Cannot but' uses a base verb in formal writing.

🔹 "I can't help feeling uneasy when a friend risks everything on one wager."

🔹 "The lucky winner could not but celebrate after receiving her massive winnings."

Key Sentence Pattern

"I can't help hoping for the jackpot, though with these odds I may well lose my wager."
