表現 expressions(複数形)
増やしたい I'd like to increase/I want to increase
「英会話初心者で話すのが難しいので、まずは趣味や仕事などよく出る話題で使える表現を増やしていきたいです」というのは Because speaking as a beginner English conversation learner is difficult, first of all I would like to increase the expressions I can use regarding topics that come up often in areas like work and hobbies と表現できます。
参考になれば幸いです。
