When Are Letters Capitalized in Greek?

The Greek alphabet has both uppercase (κεφαλαία) and lowercase (πεζά) forms, similar to the Latin alphabet. Knowing when to use each is crucial for proper grammar and clarity. Here are the fundamental rules:

1. Capitalizing the First Letter of a Sentence

Just like in English, the first letter of any sentence in Greek is always capitalized. This rule applies to both regular text and dialogue.

Example:

Καλημέρα! Πώς είστε;

(Good morning! How are you?)

2. Capitalizing Proper Nouns

All proper nouns in Greek begin with a capital letter. This includes:

3. Titles and Headings

In Greek, only the first word of a title or heading is capitalized, unless the title contains a proper noun or the word is at the beginning of a sentence. This is different from English, where most words in a title are capitalized.

Example:

Η ιστορία της Ελλάδας

(The history of Greece)

4. Days, Months, and Holidays

Unlike English, the names of days of the week and months are not capitalized in Greek unless they start a sentence. However, holidays and religious celebrations are capitalized.

Examples:

Οκτώβριος (October) – only capitalized at the start of a sentence.

Χριστούγεννα (Christmas) – always capitalized as a holiday.

5. Formal Titles and Honorifics

When addressing someone with a formal title or honorific, the title is capitalized if it precedes the name, similar to English.

Example:

Κύριος Παπαδόπουλος (Mr. Papadopoulos)

6. The Pronoun “You” in Letters

In formal written Greek, the pronoun “you” (εσείς) and its related forms are sometimes capitalized (Εσείς, Σας, Σου) to convey respect, particularly in official or business correspondence. This convention is becoming less common but is still considered polite.

7. Acronyms and Abbreviations

Acronyms are written in all capital letters, just like in English. For example, ΟΗΕ stands for Οργανισμός Ηνωμένων Εθνών (United Nations Organization).
