The grammar pattern "V-て + くる" is used to indicate an action or state that has continued from the past up to the present, or a change that begins to manifest (physically or emotionally). It also describes movement toward the speaker. This pattern often conveys a sense of progression or development, and can be used to describe both physical and emotional changes. For example, "だんだん寒くなってくる" means "it's getting colder and colder," implying a gradual change in temperature. Similarly, "最近、少しずつ漢字が分かってくる" means "I've been gradually learning Chinese characters," indicating a slow but steady progress. This pattern can also be used to describe movement toward the speaker, as in "雨が降ってくる" (the rain is coming towards us).
