personality; tend to~; sensitivity towards~
Describes a person's tendency or sensitivity, often forming nouns like 'weak to cold' or 'lonely person'.
This pattern turns an adjective into a noun that describes a person who tends to feel or act in that way. It's like saying 'a person who is sensitive to cold' or 'a person who gets lonely easily'. You often see it in words like 寒がり (someone who feels the cold), 暑がり (someone who feels the heat), and 寂しがり (someone who gets lonely). It's more about a personality trait or habit than a temporary state. For example, you might say '彼は寒がりだ' meaning 'he is sensitive to cold' or 'he tends to feel cold'.
