What is follow suit?

"Follow suit" is an idiomatic expression with origins in card games, particularly those like bridge, spades, and hearts. The phrase refers to the rule in these games where players must play a card from the same suit as the one that was led, if they have one. Over time, "follow suit" has been adopted into everyday language with a broader meaning.

In general use, "follow suit" means to imitate someone's actions or to do the same thing as someone else. For instance, if one company starts a new trend or strategy and other companies adopt the same practice, those companies are said to be "following suit."

The expression is often used in contexts where conformity, influence, or adopting similar standards is involved. It highlights the human tendency to emulate the actions of others, especially in situations involving social or professional dynamics.
