Icelandic to Lithuanian: keep identity separate from inflection
Do not turn a patronymic into a Lithuanian family assumption
An Icelandic last-name component often identifies a parent rather than a hereditary family surname. People travelling together may therefore have different last-name components without that indicating a different family relationship. Preserve their official full names in Lithuanian bookings and lists rather than manufacturing a shared surname.
“Ég heiti Anna” can be “Mano vardas Anna.” Keep the name the person supplies. Lithuanian grammar may inflect a name in running text, but that is different from altering the official form copied into an identity field. If a source name appears in an Icelandic case form, recover its base form before deciding how to use it in the Lithuanian sentence.
A suffixed article does not require a new Lithuanian word
Icelandic often attaches a definite article to the noun. Lithuanian does not have a matching article system, so an attached article need not produce an extra demonstrative in every translation. Identify the referent and write a natural Lithuanian noun phrase. Repeating this or that unnecessarily can add contrast that the Icelandic source never intended.
At the same time, do not discard a meaningful distinction between one known item and a newly introduced item. If several tickets or documents are involved, a name or descriptive phrase may preserve identification more clearly than a bare noun. The target reader must still know which item to bring, sign, or return.
Case should follow the Lithuanian verb
Icelandic verbs can govern accusative, dative, or genitive objects. Lithuanian also uses case, but the corresponding verb does not necessarily select the same one. “Ég hjálpa þér” becomes “Aš tau padedu.” This useful alignment does not justify transferring the object case of every other verb about people or assistance.
Expressions of experience need the same whole-sentence treatment. “Mér er kalt” is “Man šalta.” Both describe a person feeling cold, but Lithuanian does not need to reproduce every visible Icelandic word. Keeping a nominative-style I merely because an English gloss uses I would miss the structure of both languages.
Gender and address require Lithuanian choices
Icelandic noun gender includes a neuter class, whereas Lithuanian ordinary noun agreement does not reproduce that same three-way system. Choose the Lithuanian noun and let its grammar govern related adjectives. An Icelandic neuter form is not a reason to leave a Lithuanian adjective without the agreement its noun requires.
For direct address, Icelandic þú does not automatically establish the correct Lithuanian tu versus polite jūs choice for every unfamiliar recipient. Follow the actual relationship and purpose of the message. Keep person and number consistent across verbs and descriptions. Finally, retain Lithuanian diacritics in the translated prose while preserving Icelandic þ, ð, and accented vowels inside official names that a recipient may need to recognize or search for.
