I am coming up with constituency tests to distinguish between complements and adjuncts. But I was thrown off by the fact that I can coordinate "the jam to Pam on a holiday" as if it is a constituent. But "to Pam" and "on a holiday" should be adjuncts of the verb phrase, so they shouldn't form a phrase with "the jam" without also including "sold".
- They sold [the jam to Pam on a holiday] and [the flan to Don on a Monday].
I suppose the adjuncts could've been adjoined to the verbal projection before the verb moved, but I wanted to see what other analyses people gave, if mine was even correct.
