In English, a boy who looks like and behaves like a girl may be referred to as "effeminate" or "feminine." However, it's essential to approach such terms with sensitivity and respect, as they can carry certain connotations and may not fully capture the individual's identity or experiences.
It's essential to remember that gender expression and identity are diverse and multifaceted, and individuals should be allowed to express themselves authentically without judgment or prejudice. If you're unsure about the appropriate terminology, it's always best to ask the individual how they identify and what terms they prefer to use. Using inclusive and respectful language is important to foster understanding and create an accepting environment for everyone.
