Questions & Answers about Ég geri það mikilvægasta fyrst.

Why is it geri and not gera?

Gera is the dictionary form, meaning to do / to make.
In the sentence, the verb has to match ég (I), so it becomes geri, the 1st person singular present tense.

A few present-tense forms of gera:

• ég geri — I do
• þú gerir — you do
• hann/hún/það gerir — he/she/it does
• við gerum — we do
• þið gerið — you (plural) do
• þeir/þær/þau gera — they do

So Ég geri ... simply means I do ...

What does það mean here?

Here það does not feel as strongly like English that as it often does in other contexts.

In það mikilvægasta, it helps create a noun-like phrase meaning:

• the most important thing
• what is most important
• the most important one

So the whole phrase það mikilvægasta works as the object of the verb.
