axis 與 axes 的用法區別
- axis 是單數名詞，指一條「軸線」、「中心線」或「座標軸」。
- axes 是 axis 的複數形式，讀音為 /ˈæk.siːz/。
- 在數學、科學或地理領域，axes 常指兩條或多條相互垂直的軸，例如座標系的 X 軸和 Y 軸。
- 注意 axes 也是 axe/ax（斧頭）的複數形式，讀音相同，但意義完全不同，需根據上下文判斷。 EN: The Earth rotates on its axis once every 24 hours. 翻譯: 地球每24小時繞其自轉軸旋轉一圈。

常見錯誤
What are common mistakes with "Axis"?Which "Axis" sentences look correct but are wrong?
×The graph has two axises.
✓The graph has two axes.
The plural of 'axis' is irregular: 'axis' → 'axes' (pronounced /ˈæksiːz/). Using 'axises' is incorrect.
×Earth rotates on axis.
✓The Earth rotates on its axis.
When referring to a specific, known axis (like the Earth's rotational axis), the definite article 'the' is usually required. It's also common to use a possessive pronoun (its, their) before 'axis'.
×The line is parallel with the axis.
✓The line is parallel to the axis.
The standard preposition used with 'parallel' is 'to', not 'with', when describing alignment with an axis.
×The axle of the Earth is tilted.
✓The axis of the Earth is tilted.
'Axis' refers to an imaginary line about which a body rotates. 'Axle' is a physical rod or shaft on which wheels rotate. They are different concepts.
×Label the x-axis and y-axis.
✓Label the x-axis and y-axis. (or X-axis and Y-axis)
When referring to specific axes in a coordinate system (like x, y, z), it is standard to use lowercase letters (x-axis) or sometimes initial capitals (X-axis). Using a capital 'X' and 'Y' in the middle of a sentence for the axis name is not standard. The hyphen is also important.
×We need to choose an axis for our analysis.
✓We need to choose an axis for our analysis. (Context dependent)
This sentence is grammatically correct but may be conceptually misleading. In many contexts (e.g., a 2D graph), you don't choose 'an' axis in isolation; you work with a system of axes (e.g., 'a pair of axes', 'the coordinate axes'). 'Axis' is a countable noun, so ensure the article (a/an/the) matches whether you mean one specific axis or the system.
