Acronyms and Abbreviations
We write acronyms without periods in between (yes to ΦΠΑ, no to Φ.Π.Α.). We write their expanded forms in capitalized lowercase letters (e.g., Φόρος Προστιθέμενης Αξίας). If there is a chance that visitors might not understand an acronym or abbreviation, we write it out in full the first time it is mentioned. We then use the abbreviated form everywhere else. If the abbreviated form does not exactly match the full form, we include it in parentheses.
➔ First use: Δήλωση Οικονομικών Συμφερόντων (ΔΟΣ)
➔ Second use: ΔΟΣ
If the acronym or abbreviation is widely known, such as ΦΠΑ or ΑΕΙ, we can use it from the start.
Abbreviations
Generally, we follow Modern Greek Grammar. For some of the most common cases, we use the following forms:
➔ κ.λπ. (Et cetera)
➔ κ.ά. (Et cetera)
➔ π.χ. (for example)
➔ χλμ. (kilometers)
➔ τ.μ. (square meters)
➔ π.μ. (a.m.)
➔ μ.μ. (p.m.)
➔ ν/σ (bill)
➔ κ. (Mr./Ms./Misters/Mesdames)
Numbers
We write out the number when a sentence begins with it. Otherwise, we use the numeral. The same applies to ordinals.
➔ One out of 5 cases is the following.
➔ Keep the 1st test for reference.
Sometimes it seems awkward to use the numeral. If it's an expression where numbers are typically written out, we leave it that way.
➔ The first of the first
Phone Numbers
We use dashes without spaces between the numbers. We use the country code when addressing visitors from other countries. In mobile UIs where calling can be done directly, we include only the number.
➔ 211-555-6789
➔ +30-211-555-6789
➔ 2115556789
Dates
Generally, we write out the day of the week and the month.
➔ Δευτέρα, 3 Φεβρουαρίου
Fractions and Decimals
We write fractions in words.
➔ Yes: two-thirds
➔ No: 2/3
We use decimals when a number cannot be written as a fraction, e.g., 39.2.
Percentages
We use the % symbol instead of writing out “percent.”
Ranges
We use a dash to indicate a range of numbers.
➔ The process takes 10-15 days.
Currency
We place the euro symbol before the amount. We use a comma for subdivisions of the euro. The same applies to other currencies.
➔ €20
➔ €19,75
➔ $10
Temperature
We use the degree symbol and a capital C for Celsius.
➔ 23ºC
Time
We use numerals and π.μ. or μ.μ. with a space in between. We do not include minutes for exact hours.
➔ 9 π.μ.
➔ 9:30 π.μ.
We use a dash between different times to indicate a time period.
➔ 9 π.μ.-6 μ.μ.
Exclamation Mark
We use the exclamation mark sparingly and never more than one. It is necessary in imperative sentences.
➔ Be careful!
We never use it in failure messages or notifications. In general, we avoid it!
