Here is “fully” used in a sentence: “She was fully aware of the risks before she signed.”

“Fully” is an adverb.

The word “fully” comes from Old English. From Old English fullice, from full + the adverbial suffix -ly.

“Fully” is a very common word in modern English, usually learned at around the A2 level.

Fully means completely, with nothing left out, while partly, or partially, means only in part, to some extent. A fully charged battery is at one hundred percent; a partly charged one still has room to fill. The two words sit at opposite ends of the same scale of completeness.

Yes. Fully signals that something is complete or total, with nothing missing — fully paid, fully booked, fully recovered. It leaves no remainder or exception. When you want to stress that every part is covered and the state is total, fully is the natural word to use.

You might say, 'I fully understand your concern,' or 'The order has been fully refunded.' In each case fully stresses that the action or state is complete — total understanding, a whole refund — with nothing held back or left out.
