+## Connectives
+
+Connectives exist to link noun phrases and verbs together into larger
+noun phrases and verbs. They can also be used to link together sentences. There
+are four simple connectives: `fa` (OR), `fe` (AND), `fi` (connective question),
+`fo` (if-and-only-if) and `fu` (whether-or-not).
+
+### OR
+
+```
+ro au madsa lo spalo fa lo hafto?
+Do you want to eat an apple or an egg?
+```
+
+### AND
+
+```
+ro au madsa lo spalo fe lo hafto?
+Do you want to eat an apple and an egg?
+```
+
+### If and Only If
+
+```
+ro 'amwo mi fo mi madsa hafto?
+Do you love me if I eat eggs?
+```
+
+### Whether or Not
+
+```
+mi 'amwo ro. fu ro madsa hafto.
+I love you, whether or not you eat eggs.
+```
+
+### Connective Question
+
+```
+ro au madsa lo spalo fi lo hafto?
+Do you want to eat apples and/or eggs?
+```
