How to Choose the Right Synonym
For a Weak Argument
Choose unconvincing, flimsy, inadequate, weak, or ineffective.

Choose underwhelming, lackluster, mediocre, or unimpressive.
For example:
The team’s performance was lackluster.

For example:

This suggests that he did not put much effort into the attempt.
For Poor Quality
Choose subpar, mediocre, shoddy, or bland.
For example:

These words are useful when criticizing products, services, work, or experiences.
For Lack of Power
Choose ineffective, underpowered, or toothless.

The new regulations were criticized as toothless.
This means the regulations existed but did not have enough power to make a meaningful difference.
For Casual or Slangy Writing
