What does the phrase "words are but wind" mean?

The phrase "words are but wind" implies that spoken words can be insubstantial and fleeting, much like the wind. It suggests that what people say may not hold much weight, value, or permanence. The essence of this phrase is a reminder that actions often speak louder than words; mere promises or statements can be easily forgotten or disregarded, while tangible actions and consequences have more significance.

This saying can also reflect skepticism regarding the reliability or sincerity of someone's statements. For instance, in a context where someone is making grand claims without any follow-through or evidence, one might use this phrase to highlight the lack of substance in their words. Overall, it serves as a caution against placing too much trust in what is merely spoken, advocating for a focus on tangible results instead.
