Alleen
Alleen is a common Dutch word with two core functions. As an adverb it means only or merely, and as a predicative or adjectival form it means alone or by oneself. In sentences it can express limitation, emphasis, or solitude: for example, Ik ben alleen (I am alone) and Het is alleen een grap (It is only a joke). The sense is often determined by context and intonation.
In combination with other words, alleen frequently appears in phrases such as alleen maar, which adds emphasis
Etymology and usage notes: linguists trace alleen to older Dutch forms connected with the idea of wholeness
