Lojban Through Dialogues
Lesson 1. Hello, Goodbye, and Leaving
Lifri has just spotted Mentu at a Lojban meetup — his first time here. A real conversation rarely stops at the first hello: people introduce themselves, then someone has to run.
| Lojban | English |
|---|---|
coi .i mi'e la mentu | Hello — I'm Mentu. |
coi la mentu .i mi'e la lifri .i coi do | Hello, Mentu — I'm Lifri. Hello to you. |
mi cliva co'o | I'm off — bye! / I'm leaving — bye. |
co'o | Goodbye. |
co'o la lifri | Goodbye, Lifri. |
New words
| Lojban | Meaning |
|---|---|
| coi | hello (greeting) |
| co'o | goodbye (parting) |
| mi'e | I am … / my name is … |
| la | name-tag — turns the next word into a name |
| do | you |
| cliva | x₁ leaves x₂ — with mi and co'o: mi cliva co'o = "I'm leaving — bye" |
Grammar note:
A single Lojban word can be a complete sentence. coi on its own means "I greet you." co'o means "I bid you farewell." mi cliva co'o chains two common moves: you say who is leaving (mi cliva), then the parting (co'o) — very natural in online and offline conversations when someone has to go.
Practice dialogue
A little later, Linto walks up to Mentu.
| Lojban | English |

coi do .i mi'e la linto | Hello. I'm Linto. |
coi .i mi'e la mentu | Hello. I'm Mentu. |
mi cliva co'o .i co'o la mentu | I'm heading out — bye, Mentu! |
co'o la linto | Goodbye, Linto. |
New word
| Lojban | Meaning |
|---|---|
| .i | sentence boundary — separates two sentences (like a spoken full stop) |
Grammar note:
.i is written with a dot before it. You can chain as many sentences as you like: coi .i mi'e la mentu .i mi cliva co'o.
