I like the word: Inoubliable. Which means unforgettable in french. Normally, the word I'd like would be more meaningful and complicated, but unforgettable is so powerful because it also incorporates my other favourite words: Infinity, everlasting, always and it's meaningful. That is why I like the word inoubliable. Also because I think french words are fancy!
I like the words of adjective,as they are easier to remember and sounds good for spelling or pronouncing like : Wonderful, beautiful useful etc... French words are easier to spelling as they have a rule of how to spelling, so I like them as well.
Anticoagulant and deoxyribonucleic acid.
And the word world just sounds weird.
