だけあって— Living Up to It

• 彼は元プロだけあって、動きが違う。

  Kare wa moto puro dake atte, ugoki ga chigau.

  As you'd expect from a former pro, his movements are on another level.

  Noun 元プロ + だけあって explains the impressive movement as fitting his background.

• 毎日練習しているだけあって、上達が早い。

  Mainichi renshuu shite iru dake atte, joutatsu ga hayai.

  Precisely because she practices every day, she improves fast.

  Plain form している + だけあって links daily practice to the deserved fast progress.

• 有名な観光地だけあって、人が多い。

  Yuumei na kankouchi dake atte, hito ga ooi.

  Being a famous tourist spot, it's fittingly crowded.

  な-adj 有名な + だけあって presents the crowd as the natural result of its fame.

• ・The result should be admirable or naturally explained — not a negative surprise.
• ・A variant だけのことはある works as a sentence-final 'it lives up to it'.
• ・Register: neutral, common in speech and writing alike.
