<p>WHAT THE HECK I'M SICK OF GRAMMAR AILHGALHELAKEJLKAJERWT</p>
<p>my sister just told me to "eat healthy" and then it hit me</p>
<p>is "eat healthy" grammatically incorrect?</p>
<p>you’re right.
you can practice healthy eating/ be a healthy eater. but you eat healthily.
healthy is an adjective. healthily is an adverb.</p>
<p>when you say “eat healthy” don’t you mean to say “eat healthy stuff”?
If you say to “eat healthily” wouldn’t it mean to make the act of eating healthy?</p>
<p>“Eating healthy” implies that you eat something that is named “healthy.” I’m pretty sure it’s “Eating healthily.”</p>
<p>adverbs describe VERBS, and end in -ly. How is he eating? Healthily!</p>
