What is the comparative and superlative meaning if word tactful?

"Tactful" doesn't have comparative or superlative forms in the typical way that adjectives like "big" (bigger, biggest) do. This is because "tactful" is already an adjective expressing a high level of skill in handling sensitive situations.

However, we can use other words to express varying degrees of tactfulness:

* More tactful/less tactful: These phrases can be used to compare the level of tactfulness between two people or actions. For example, "She was more tactful than he was in dealing with the customer complaint."

* Extremely tactful/remarkably tactful/exceptionally tactful: These phrases emphasize a high degree of tactfulness. For example, "The diplomat was extremely tactful in his negotiations with the foreign leader."

In short, while "tactful" itself doesn't have a comparative or superlative form, we can use other words and phrases to convey varying levels of tactfulness.
