Use lowercase "n" when referring to a subsample or a specific group within a larger study. For example, if a study looked at 100 people total, but only 45 were men, you would write: "The male subgroup (n = 45) showed significant improvement".
Use uppercase "N" when referring to the total population or the entire sample size of a study. For example: "The total sample size for the study was N = 100".
The correct term in English is silver dirhams. The word comes from the Arabic dirham (Arabic: dirham, plural darāhim), a silver coin widely used in the medieval Islamic world. In English historical and archaeological writing (singular: dirham, plural: dirhams). You sometimes see dirhems as a transliteration variant, usually reflecting:
French or older European scholarship
attempts to reflect pronunciation differently
inconsistent transliteration from Arabic
However, in modern English-language scholarship, especially in archaeology and numismatics, dirhams is overwhelmingly preferred.Quick rule
Use: dirham / dirhams ✔
Avoid in English: dirhem / dirhems (unless quoting a source)
Consistency is key, so always follow the specific guidelines of your style guide.
Style guide recommendations
No spaces: Most major academic and book publishers recommend using the em dash without spaces on either side. This is considered standard for most forms of writing.
Example: "The flight—which had already been delayed three times—was canceled."
Spaces around the dash: Newspapers, including those that follow AP style, typically use spaces around an em dash.
Example: "The flight — which had already been delayed three times — was canceled."
Why the difference? The spacing in newspapers improves readability in narrow columns, while the lack of space is often preferred for book publishing to create a more cohesive look.
Tips for using em dashes with spaces
Be consistent: Whichever style you choose, apply it consistently throughout your document.
Consider context: The most important rule is to follow the style guide you are required to use (e.g., for a specific publication, academic assignment, or newspaper).
Think about a thin space: For even more professional typesetting, a very small "thin space" can be used on each side of an em dash instead of a full space.
The Problem With Em-dashes
In some langauges, m-dashes are frequently used as punctuation marks. In English they are seldom used. BUT the (over)use of m-dashes is a commonly recognised symptom of a text being written by AI, and for that reason, should be avoided as much as possible in acadmic writing, they create a bad impression. I suggest removing as many as you can replacing them with other punctuation where it is possible.
Correct usage: The text before the citation is contrasted with the work cited after "cf." Example: "...while theory supports the claim (cf. Jones 1992)." Example: "...the shield lacked the 'umbo,' the metal-boss of Waltharius (cf. lines 772 and 776)."
Incorrect usage: Using "cf." to mean "see" or "see also" is considered an error.
Incorrect: "...while theory supports the claim, see also Jones 1992."
Correct: "...while theory supports the claim (see also Jones 1992)."
The pronunciation of the Past Simple made easy. In English, past tense verbs with an -ed ending are pronounced in three different ways:
[t]
[d] or
[Id].
Why the Sound Changes
If you place your fingertips on the front of your neck, and pronounce the following pairs of words, you should feel some vibration on your fingers with one of them:
vow | fake (vvv | fff)
zebra | snake (zzz | sss)
The vibrating ones are "voiced" sounds. [v] [z].
When we pronounce "voiceless" sounds (such as /p/, /f/, /s/, /ʃ/, /ʧ/ or /k/), our vocal chords do not vibrate.
This vibration or lack of vibration then carries forward to the following sound in the word. Therefore, this vibration or lack of vibration explains why we pronounce the past tense of verbs in three voiced or voiceless ways: [t], [d] or [Id].
1) If the verb ends in /t/ or /d/, this will cause the past simple ending to be pronounced /Id/ (or /əd/).
Examples, wanted, visited, edited, ended, threaded (beads).
2) If the verb ends in a voiceless sound, such as /p/, /f/, /s/, /ʃ/, /ʧ/, /θ/, or /k/, the past simple ending is pronounced as the voiceless /t/ (with no vocal chord vibration)
For example, stoppedn popped, talked, laughed, reached, kissed and washed.
3) If the verb ends in another voiced sound [b, g, ð, v, z, ʒ, dʒ, m, n, ŋ, r, l], cause the “-ed” ending to be pronounced as a voiced [d].
For example, Loved, rolled, cleared, banged, played, allowed, begged, breathed, raised, claimed, banned.
