How to say "architect" in Japanese

• 建築家けんちくかCommon
  nounThe common word for an architect as a profession: a person whose work is designing buildings. Choose this when speaking of the occupation or of noted designers of buildings.

• アーキテクト
  nounThe katakana loanword. Less common than 建築家, it tends to appear in specialized contexts and is not the everyday word for a person who designs buildings.
• 建設者けんせつしゃ
  nounDespite the gloss, this denotes a person who builds or constructs rather than one who designs, so it is seldom the word you want for 'architect'; for the profession, 建築家 is the natural choice.

Use 建築家 for an architect in the ordinary sense of a person who designs buildings; 「アーキテクト」 is a less common loanword heard in specialized contexts, while 建設者 really means a builder and is rarely the right choice.
