The spelling of "wert saddle" is quite unusual and requires some explanation. The word "wert" is pronounced [wʌrt] and is an archaic form of "were not", meaning "were not". The word "saddle" is pronounced [ˈsædl] and refers to a seat for a rider on the back of an animal. Together, "wert saddle" means "if you were not riding a saddle". While the spelling may be puzzling, the pronunciation is straightforward if you understand the IPA phonetic transcription.
