As we have private classes, can we have semi private classes? Or can we say semi intensive courses? I mean are the terms semi private and semi intensive correct in English?
The prefix "semi-" is widely used to mean "to a degree", "partly", "almost". So terms like "semi-intensive" and "semi-private" would be fine, I feel, although they require a hyphen, unlike more established words such as "semipermanent" and "semidarkness".
