What does Lina mean?
As an Arabic name Lina (لينة, lina) means 'a tender young palm tree', a sense that appears in the Quran (Surah al-Hashr), and connects to the root l-y-n ('soft, tender'). Disambiguation: in Europe Lina is commonly a short form of names such as Carolina or Angelina, an unrelated source.
What does Yara mean?
In contemporary Arabic naming Yara (يارا) is most often glossed 'small butterfly'. The etymology is not firmly settled: it is also linked to the Persian yar ('friend, companion, helper'). A separate, unrelated Yara/Iara comes from Brazilian Tupi mythology, so cross-culture care is warranted.
