More than normally; almost like two times as much, often for two reasons at the same time.
用法パターン：
doubly [adjective]
よくある間違い：
Learners sometimes say *"double happy"* or *"double careful"* instead of *"doubly happy"* or *"doubly careful"*. Use **doubly** before adjectives and adverbs. Another mistake is using *"doubly more"* (e.g. *"doubly more important"*); say either *"doubly important"* or *"much more important"*, not both together.
