An "itinerant" is someone who wanders and drifts without a fixed home; a vagabond or homeless person. A "recipient" is someone who receives something from someone else. A "witness" is someone who sees an event (usually an accident or crime). "Host" and "guest" are antonyms.

Note that "freshmen," "sophomore," and "senior" are somewhat related in meaning in so far as their use to refer to someone in high school with a particular level of education. "Senior" may seem to be related to these words, but in this case the noun has a very different meaning, referring to someone who is old in age: consider the phrase senior citizen or "pensioner." "Pensioner" is closest in meaning to senior. "Child" and "infant" are clearly related but do not come close in meaning to pensioner.

"Financier" can refer to someone who invests financially in some venture. This kind of individual can also be referred to as a "backer." The other nouns are not at all related to money or finances.
