Applicative extends Apply and not Semigroupal and Functor

[dadepo]

Chapter 6 has it that:

Applicative extends Semigroupal and Functor. It provides a way
of applying functions to parameters within a context. Applicative is
the source of the pure method we introduced in Chapter 4.

That is not quite correct. Applicative extends Apply and not Semigroupal and Functor as stated above. Even though this can be said to be the case indirectly since Apply extends Semigroupal and Functor, but stating it as above could lead to confusions.

It is better to state that Applicative extends Apply and Apply then extends Semigroupal and Functor

It provides a way of applying functions to parameters within a context

Is not particularly correct. It should be

It provides a way of applying functions inside a context to parameters within a context
