  • Yeah, in grad school I taught myself field theory with this book.
  • quantum field theory
  • effective field theory
  • unified field theory

So now you equate some field theory with a full string theory.

Morphology

field + theory

The phrase is compositionally transparent: 'theory' (a set of ideas) combined with 'field' (a domain or region, especially in physics/maths) yields 'a theory about fields' which a B1 learner who knows both words can reasonably infer. Although the full technical content requires subject knowledge, the basic meaning is directly derivable from the constituents and follows a common noun-noun naming pattern.

Etymology

Field theory gets its name from imagining a wide field where every spot has a number (like temperature) and those numbers can change and affect nearby places. That's why field theory means a 'theory' that explains how such fields across space and time behave and make things happen.
