Morphology
sinew + of
The meaning arises via a metaphorical extension: 'sinew' literally denotes a tendon (something that transmits force) so 'sinew of X' can be inferred as the main source of strength or support for X if the learner knows 'sinew' and 'of'. Because this is a figurative, somewhat literary use rather than a fully compositional, everyday pattern, it is predictable but not immediately transparent to an average B1 learner.
Etymology
Sinew of comes from the old word sinew, a tough cord that joins muscle to bone and gives the body strength. So, sinew of is used to mean 'the main source of strength' in something.
