Бог(и) этимологии: pray, do sit down.

[furia_krucha]

Слова prayer („молитва“) и precarious („сомнительный“, „No word is more unskillfully used than this with its derivatives. It is used for uncertain in all its senses; but it only means uncertain, as dependent on others ...“ [Johnson]) восходят к одному и тому же латинскому глаголу: precari - „выпрашивать“.
