～そうだ acts like a 形容動詞 and is only used with adjectives or verbs. It just can't be used with plain nouns．Its usages have significant differences in grammar. There are two grammatical ways it can be used. In this lesson, we will focus on how it is used when it attaches to the 連用形.
From the outward appearance, ～そうだ expresses the speaker's intuitive subjective guess on the nature, quality, or properties of something or someone. The statement isn't proven. So, if obvious, it's not applicable. This is like "seem to be (doing)". ～そうだ attaches to the 連用形 for verbs but the stems of adjectives for conjecture.
| 動詞 | 降る＋そうだ→降りそうだ | 形容詞 | 面白い＋そうだ→面白そうだ | 形容動詞 | 簡単＋そうだ→簡単そうだ |
The negative can be ～なさそうだ or ～そうじゃない. One may be more preferable depending on the situation and or the opinion of the speaker. With adjectives in the negative and よい, さ should be inserted. So, ～なさそうだ and よさそうだ.

18. 忙しそうです。 VS 忙しいようです。

Nuance Note: As this shows, ～そうだ shows something from an intuitive judgment based on observation.You get the sense that the person is busy. Maybe he's constantly looking at his clock. ～ようだ indicates that the judgment is based on actual knowledge of the person's situation. You may have heard that he was busy, or you know information concerning his work schedule.

From 白夜行 by 東野圭吾.
Grammar Note: Remember that this structure is adjectival. So, you can get forms like ～そうな and ～そうに.
Word Note: 初老 originally meant someone in one's forties. As people now live longer, some consider it to mean mid-fifties to even early sixties.
Inserting -さ
Again, with よい and ない, さ is inserted. This gives よさそう and なさそう. As for the auxiliaries ～たい and ～ない, ～そうだ attaches to the stem. However, さ is being attached more and more. Even for adjectives that end in ない like ぎこちない (awkward), ～さ is being attached. The negative is ～そうではない, but you can also use ～な（さ）そうだ. However, something like "知らなそうだ" is correct. You still get examples like 20, though.
