Learn English – “partially cloudy” or “partly cloudy”

Partially is mostly used in contexts involving non-tangible description of things.

Example:

Your views are partially correct.

Whereeas partly is preferred for tangible description.

Example:

The construction is partly built on stone.

Moreover, 'partially' is more abstract and concrete w.r.t usage than that of 'partly'.

Try to think of it this way:

Specific and concretely describing

'half of the liquid' partly goes more with this.

Vague and non specific description

'Some of the liquid' partially is more apt here.

If I went home for dinner, I’d have a soft drink is an example of the Second Conditional (I’ve changed the wording slightly to make the English sound more natural). The Second Conditional is used for a situation when the action envisaged in the if clause is unlikely. It is normally used to say what might happen now or in the fairly near future. However, the construction could also be used by a speaker describing something in the past, particularly in some kind of narrative. Used this way, it suggests that on those occasions on which the speaker went home for dinner in the past he was in the habit of having a soft drink. If I went home for dinner, I had a soft drink can be used in the same way (but it cannot be used as an alternative to the normal use of the Second Conditional).
