Not yet developed; not yet having a finished shape. You use it for something that exists but has not grown into what it will become.

It is common for thoughts and plans: an unformed idea is one you can feel but cannot explain yet, still cloudy in your head. It also works for people — an unformed personality, unformed opinions — meaning young and still changing, and this use is gentle rather than insulting; it says 'not finished' rather than 'bad'.

It is common for thoughts and plans這個字常用在想法和計畫上： an unformed idea is oneunformed idea是那種 you can feel but cannot explain yet你感覺得到卻還說不清楚的想法， still cloudy in your head腦子裡還是一團模糊。It also works for people它也用在人身上 — an unformed personality, unformed opinions像是unformed personality（還沒定型的性格）、unformed opinions（還沒成形的看法） — meaning young and still changing意思是還年輕、還在變化， and this use is gentle rather than insulting而這種用法是溫和的，不是在批評；it says 'not finished' rather than 'bad'它說的是『還沒完成』而不是『不好』。

Then there is a more physical use, closer to the plain meaning of the parts: unformed clay, unformed bones in a baby, something with no clear shape at all. Doctors and biology books use it that way.

Then there is a more physical use接著還有一個更具體的用法， closer to the plain meaning of the parts更接近字面的意思： unformed clay, unformed bones in a baby像是unformed clay（還沒成形的黏土）、unformed bones in a baby（嬰兒還沒發育完全的骨頭）， something with no clear shape at all完全沒有明確形狀的東西。Doctors and biology books use it that way醫生和生物學書籍就是這樣用的。

Take care with the feeling of the word. Unlike many un- words, it is not usually a criticism; it is closer to 'early', 'raw', 'still becoming'. Writers like it for exactly that, because 'unformed' admits that something real is there while being honest that it is not ready.

Take care with the feeling of the word要注意這個字的語感。Unlike many un- words不像很多un-開頭的字， it is not usually a criticism它通常不是在批評； it is closer to 'early', 'raw', 'still becoming'比較接近『還早』、『生的』、『還在長成』。Writers like it for exactly that作家就是喜歡這一點， because 'unformed' admits that something real is there因為『unformed』承認了有個真實的東西存在， while being honest that it is not ready同時老實說它還沒準備好。

It is a somewhat literary and thoughtful word — you meet it in books and serious articles more than in conversation, where people would just say 'not clear yet' or 'still working it out'.

It is a somewhat literary and thoughtful word這是個有點文學性、帶思考感的字 — you meet it in books and serious articles你在書籍和嚴肅文章裡會遇到它 more than in conversation比在對話裡更常見， where people would just say 'not clear yet' or 'still working it out'對話裡人們就只會說『還不清楚』或『還在想』。
