Если условные (придаточные) предложения содержат глаголы had, were, could, should, то возможно бессоюзная связь главного и придаточного предложений. В этом случае эти глаголы ставятся перед подлежащим, союз if опускается. Такой порядок слов называется инверсией.
Перевод таких предложений следует начинать с союза «если бы».
E.g. Had he a dictionary, he could translate the text. – Если бы у него был словарь, он смог бы перевести текст.
Should he come, ask him to wait. – Если он придет, попросите его подождать.
