Expert writing Tips
Best practice
When using "they have shown", ensure the pronoun "they" clearly refers to a specific group or entity to avoid ambiguity. For instance, instead of saying "They have shown great resilience", specify who "they" are: "The team members have shown great resilience."
Common error
Avoid using "they has shown", as this violates subject-verb agreement. Remember that "they" is a plural pronoun and requires the plural form of the verb, which is "have". For example, it's correct to say "They have shown interest", not "They has shown interest".
