Strongly means with great force, intensity, or conviction. When you push strongly against a heavy door, you're using a lot of your physical strength. When you feel strongly about something, your emotions or beliefs run deep and won't easily change.

The word describes doing something with power rather than holding back. A strongly worded letter uses forceful, direct language that leaves no doubt about the writer's position. If you strongly disagree with someone, you think they're clearly wrong and you're ready to explain why.

Notice how strongly can apply to physical actions, emotions, and ideas. Wind blows strongly during a storm. A bridge must be strongly built to support heavy traffic. Someone might believe strongly in telling the truth, meaning that value guides their choices even when lying would be easier.

The word suggests confidence and commitment. When you recommend something strongly, you're urging someone to act: “I really think you should do this.” That confidence matters: people listen differently to someone who states their case strongly rather than someone who tentatively mumbles their opinion.
