そう Look like, Appear, Seem, Have a feeling that

Caution

そう may also be used when attached to the い-Adjective, ない. In this case, there is a unique conjugation rule which we will need to be careful of. As always, い will be removed from ない before attaching そう. However, さ will be inserted between な, and そう. This creates the expression なさそう.

Note that this addition of さ does not happen with verbs. This is due to the ない that is used with negative verbs being an auxiliary verb, and not an い-Adjective. With the auxiliary verb ない, simply remove the い, before adding そう directly to the stem.

Caution

This そう is utilized exclusively to make predictions/guesses about something based on visual information. It is relatively low confidence, so should not be used for things that are obvious. In these cases, みたい would be used instead.
