appendage vs limb
「appendage」泛指生物體上任何附屬或延伸的部分，範圍較廣，包括觸角、鰭、翅膀等；「limb」通常特指四肢（手臂或腿），用於人類或動物，範圍較窄且更為具體。
appendage vs protuberance
「appendage」強調是附屬、可動或具有特定功能的部分；「protuberance」則指突出、隆起或腫塊，可能只是結構上的凸起，不一定具有獨立功能。
appendage vs extension
「appendage」通常指生物體自然生長的部分，屬於本體結構；「extension」可指機械、抽象或人為的延伸，範圍更廣，且不一定是有機體的一部分。
在口語中，當引述或提及某個特定術語時，可能會用「appendage」來指稱身體或物體的附加部分，通常帶有解釋或強調其非主體的意味。 EN: He kept referring to the small antenna as just an "appendage" of the main device. 翻譯: 他一直把那根小天線稱為主設備的一個「附屬物」。

正式寫作注意：在學術或正式文件中，「appendage」是一個精確的生物學或技術術語。然而，在口語中使用時，其含義可能較為鬆散，有時僅泛指「附加的東西」。在正式寫作中，應確保其使用符合該領域的專業定義，避免口語中那種泛指或略帶隨意的用法。

×The robot's arm is just an appendage.

Using 'just' can imply the part is unimportant or trivial, which may not be accurate. 'Appendage' is a neutral term; adding 'just' changes the meaning.
×He felt like an appendage to the team.
✓He felt like an appendage of the team.
The correct preposition when describing attachment or belonging is usually 'of' or 'to' in a different structure (e.g., 'an appendage to the main body'). For metaphorical use with a group, 'of' is more natural.
×We need to appendage a new module.
✓We need to attach/append a new module.
'Appendage' is a noun, not a verb. The correct verbs are 'attach', 'append', or 'add'.
×The appendix is an important appendage in the human body.
✓The appendix is a vestigial appendage in the human body.
Calling the appendix simply an 'appendage' is vague and biologically imprecise. It's more accurate to specify it as a 'vestigial appendage' or 'organ'.
×She decorated her bike with many colorful appendages.
✓She decorated her bike with many colorful accessories/attachments.
'Appendage' typically refers to a natural projecting part of a biological body or a primary structure. For man-made decorative additions, 'accessories' or 'attachments' is more appropriate.
