New Year neologism

The lead headline in today's Dallas Morning News was Southwest Airlines' CEO Herb Kelleher's obituary.  The first sentence is, "Herb Kelleher moved to Texas in 1962 with plans for a career in law."  Only I read it as "career-in-law," then wondered, what's a career-in-law?  I had time to decide it was when someone like Harry Bailey marries into a family business before I noticed there were no hyphens and it meant he was a lawyer.
