gestation #2

｢ハリー・ポッター｣シリーズがロンドンのウエストエンドでミュージカルとして上演されることが発表されました。
gestationには以前にUG先生が採り上げられていましたが「妊娠；懐胎期間」を表す単語（『プログレッシブ英和中辞典』小学館）。

そして，その他に今回のように「（アイデアプランなどを）温めること」という意味もあります（『プログレッシブ英和中辞典』小学館）。よってAfter a year in gestation「１年もの構想期間を経て」と解釈できます。（Koyamamoto）

'Harry Potter' play coming to British stage
(CNN) -- There's some magic coming to a British stage.
Author J.K. Rowling has announced she is developing a play based on her "Harry Potter" stories. According to her website, Rowling is working in collaboration with award-winning producers Sonia Friedman and Colin Callender on the project.
"Over the years I have received countless approaches about turning Harry Potter into a theatrical production, but Sonia and Colin's vision was the only one that really made sense to me, and which had the sensitivity, intensity and intimacy I thought appropriate for bringing Harry's story to the stage," Rowling said in a statement.
"After a year in gestation it is exciting to see this project moving on to the next phase. I'd like to thank Warner Bros. for their continuing support in this project."
