Worry vs. Concern
These verbs are synonyms but are used in different grammatical structures. This lesson will clarify their difference.
Both 'worry' and 'concern' are verbs that refer to a state of feeling anxious or upset about a situation or event. However, 'worry' can be both transitive and intransitive while 'concern' is always transitive. This lesson will further explore this difference.
Grammatical Difference
While closely related in meaning, 'worry' and 'concern' differ in terms of their grammatical structure. 'Worry' can be used both transitively and intransitively.

In its transitive usage, it means to make someone anxious about something and has a human object. 'Concern', however, is always transitive in this meaning and takes a human object, while the subject is the person or thing that causes the feeling of anxiousness. Take a look at the examples:
