Synonym discussion
Sense: adjective/1
All five words describe a willingness to believe others, but with important differences in tone and scope. 'Trusting' and 'trustful' are the closest in meaning — both describe a general tendency to assume people are honest, though 'trusting' is far more common in everyday English. 'Unsuspecting' usually applies to a specific moment: someone who does not realise they are about to be tricked, like an unsuspecting victim in a scam. 'Naive' adds the idea of inexperience — a naive person lacks the life experience to judge others' motives, so their trust is more a result of innocence than of positive expectation. 'Gullible' is the strongest and most negative: a gullible person will believe almost anything, even obvious lies. For example, a trusting child might believe a stranger's promise, a naive teenager might not recognise flattery, and a gullible adult might fall for the same email scam three times.

Etymology
The adjective 'trusting' was formed in English by adding the suffix '-ing' to the verb 'trust', which came into English from Old Norse 'treysta' — meaning to rely on or have faith in. The '-ing' suffix here turns the action of trusting into an adjective describing a person's character. The word has been used to describe a person's tendency to believe in others since at least the 16th century.
