Morphology
The phrase literally combines 'that is' + 'to say' to signal a restatement or clarification, so a learner who knows the component words can infer it introduces a clearer explanation. This discourse-marker pattern has close parallels in many languages (e.g., Spanish 'es decir', French 'c'est-à-dire'), making the function predictable for a B1 learner.
Etymology
That is to say comes from the simple idea of pointing back to something you just said and then explaining it again more clearly. Imagine pointing to that and then using say to make the meaning clear, so the phrase is used 'to give a clearer explanation'.
