貸す (かす, 'to lend') is the general-purpose lending verb, working for any object — here, a dictionary. The に marks the borrower. 辞書 (じしょ) is the standard word for a dictionary, and the よい ('good') suggests a quality or well-regarded one. The pattern [person]に[thing]を貸す is the standard ditransitive frame for lending.
