Grammar and formatting

Discover our key grammar principles.

Abbreviations

Use abbreviations consistently throughout your experience to help with predictability and usability. Do not make up your variants or notations. Write established technical abbreviations of long forms, names of organizations, and so on, consistently using uppercase letters.

Avoid abbreviations in Latin within sentences and write the English phrase instead.

Avoid using short forms of words in sentences.

Specific examples

Including/Excluding


Active and passive voice

In a sentence written in the active voice, the subject of the sentence acts. In a sentence written in the passive voice, the subject receives the action.

The active voice carries the same meaning as the passive voice, but it is shorter and more direct. Whenever possible, use the active voice rather than the passive voice.

In some cases, especially when we wish to emphasize the object modified by the action or we do not want to mention who is doing the action, use the passive voice.


American English

We use American English throughout the Mirakl platform. The following common words are spelled this way.


Capitalization

Use sentence case (uppercase letter for the first word of the sentence, then lowercase for all other words) when writing in Mirakl interfaces.


Contractions

Always use the long form of auxiliary verbs and avoid contracted forms.


Directional language

Avoid using words like above, below, left, or right in your microcopy. Actions and related descriptions should be close together to avoid using directional language. If you feel you need to add those words to your copy, reconsider the design of your page.

Adding directional language to your microcopy also makes it harder to reuse strings in a different context and creates challenges for internationalization (for example, right to left languages).


File formats

Write file formats in uppercase.


Formatting

Bold

Only use bold when referring to any UI element.


Lists

Bulleted

A bulleted list is preceded by a column. The structure of a bullet list must be consistent. If you begin the first bullet point with a verb, each bullet point on the list must start with a verb. Apply the same rule for nouns or any other kind of grammatical element.

Numbered

Use numbered lists to explain to users how to carry out a task or when priority in completing tasks matters. Never use numbered lists to enumerate a list of items (as for bullet lists).


Modal verbs

Whenever possible, do not use the following modals, as they can confuse users:

Dates, numbers, and units

Dates

For maximum clarity, use the 3-letter formatting for months, followed by day and year.

Official abbreviations for months:

  • Jan

  • Feb

  • Mar

  • Apr

  • May

  • June

  • July

  • Aug

  • Sept

  • Oct

  • Nov

  • Dec

As a secondary option and for space constraints, you may use the full numeral format (month, day, year).

Local formatting is handled by Roma.

Times and timezones

Use the 12-hour clock time convention with AM or PM in capital letters.

AM stands for Ante Meridiem, meaning before noon, and PM for Post Meridiem, meaning after noon.

Numbers

Use a period as the decimal separator and a comma as the thousands separator in English.


Pronouns

Use they, not he or she.


Punctuation

Ampersands (&)

Do not use ampersands for accessibility reasons. Spell out the word and.

Commas

Use a comma to separate independent clauses from the rest of the sentence.

If the subordinate clause is independent of the main clause, place a comma before the conjunction. The comma indicates that there are two different ideas in the sentence.

Use a comma to separate dependent phrases in front of the main clause. If the dependent phrase is in front of the main clause, place a comma between them. This improves readability.

When there are several consecutive adjectives, and the adjectives are independent, separate them with commas.

If the adjectives can be separated using “and” or if the sequence of the adjectives can be changed without changing the meaning, then separate the adjectives using a comma.

Do not use a comma in front of an infinitive.

Use a comma before a conjunction in an enumeration (Oxford comma). Separate the last noun in a list from the rest of the list using a comma.

Hyphens

Use hyphens to link words.

Never use hyphens after adverbs.

Always write attributive adjective compounds consisting of more than two words using a hyphen.

If the adjective compound consists of four or more words, place the hyphen so that the related adjectives are joined, and the adjective compound is sensibly structured.

No hyphen:

  • back office (not back-office)

  • markup (not mark-up)

  • onboarding (not on-boarding)

Hyphen:

  • drop-down


Tenses

You can use simple tenses within the Mirakl interface, meaning present, past, and future. Avoid perfect tenses (have + past participle) and continuous tenses (be + verb-ing).

Past

Present

Enter a valid period.

Future
