Shelterer → It is formed from "shelter" (from Old English *scealdor*, meaning a place of protection or refuge) and "-er" (meaning a person who). A shelterer is a person who provides or seeks shelter.
Think of someone who provides a 'place of protection' ('shelter') — the '-er' just means a person. A shelterer is someone who helps others find safety.
