Tense comparison exercises in Icelandic grammar are essential teaching tools. They stimulate students to understand the nuances of the different verb tenses. Icelandic primarily has two tenses – present and past, with no distinct future tense form. Its indicative and subjunctive moods are used to express time-sensitive sentences.

When engaging in tense comparison exercises, the focus is often on the transition between these tenses. For instance, the verb ‘að lesa’ (to read) changes from ‘les’ (reads) in the present tense to ‘las’ (read) in the past tense. Similarly, ‘að byrja’ (to start) changes from ‘byrjar’ (starts) to ‘byrjaði’ (started).

However, in Icelandic, the future is usually expressed by utilizing the present tense or by adding auxiliary verbs like ‘munu’ (will). A classic exercise is to translate sentences from English with explicit future tense into Icelandic, like “I will read” to “Ég mun lesa” (literal) or “Ég les” (conversational).

It’s also crucial to teach the conditional mood, often used with hypotheticals or politeness. For example, ‘að vilja’ (to want) changes from ‘vill’ (wants) in indicative mood to ‘myndi vilja’ (would want) in conditional mood.

Tense comparison exercises not only help students understand the structure but also the application of Icelandic tenses, contributing towards their fluency in this expressive, complex language.
