In Lithuanian grammar, prepositions play a crucial role in indicating the relationship between different elements of a sentence. They can be simple, such as « su » (with), « iš » (from), or « per » (through), or compound, formed by adding prefixes or suffixes to the simple prepositions.

Prepositions in Lithuanian have multiple uses. They can indicate direction or movement, such as « į » (to), « apie » (about), or « prieš » (against). Additionally, they can express location or position, like « už » (behind), « prie » (next to), or « viduje » (inside). Moreover, prepositions are used to establish time relationships, for example, « nuo » (since), « per » (during), or « po » (after). They also serve to mark possession, as in « be » (without), « turintis » (having), or « neturėdamas » (not having).

Learning and using prepositions correctly in Lithuanian is vital for building a strong foundation in the language. Mastery of prepositions enables one to express ideas clearly and effectively, ensuring the proper understanding and communication of thoughts and messages. Therefore, a thorough understanding of prepositions is essential for learners of Lithuanian.
