In plain English: Strongly means doing something with a lot of force, energy, or firm belief.
"She strongly believes that exercise is good for your health."
Usage: Use strongly to modify verbs that indicate force, intensity, or conviction, such as believing, opposing, or supporting. Avoid using it with adjectives like "good" or "bad," where the word very is more appropriate for simple emphasis.
Strongly comes from the Middle English word strongliche, which was formed by adding -ly to the Old English adjective strang. The term has retained its original meaning of being powerful or forceful since it entered the language.
