Present perfect continuous (vera búinn að vera að)

Describing Pregnancy

When talking about a pregnancy, you will often need to describe symptoms like nausea or sleepiness.

Are you not pregnant? Yes, and the nausea is very bad.
Ertu ekki ólétt? Jú, og ógleðin er mjög slæm.

The Present Perfect Continuous

To express that an action has been happening continuously over a period of time (the English "has/have been doing"), Icelandic combines two structures: the present perfect (vera búinn að) and the continuous (vera að).

The full formula is: [Conjugated vera] + [búinn] + að vera að + [infinitive verb]

Literally translating to "to be finished to be doing [something]", the first vera changes to match the subject. Búinn must agree in gender and number with the subject, just like an adjective. The rest of the phrase (að vera að + infinitive) never changes.

For a feminine subject like konan (the woman), use the feminine singular form búin:

The woman has been vomiting a lot because of the nausea.
Konan er búin að vera að æla mikið út af ógleðinni.
The sleepiness is overwhelming, and I have been sleeping a lot during the pregnancy.
Syfjan er yfirþyrmandi og ég er búin að vera að sofa mikið á meðgöngunni.

For a neuter subject like barnið (the child), use the neuter singular form búið:

The child has been kicking a lot during this pregnancy.
Barnið er búið að vera að sparka mikið á þessari meðgöngu.

Milestones and Advice

This aspect is common when giving advice about continuous symptoms, or describing ongoing preparations.

You have to call the midwife if you have been vomiting for a long time.
Þú átt að hringja í ljósmóðurina ef þú ert búin að vera að æla lengi.
The midwife herself has been preparing the ultrasound for us.
Ljósmóðirin sjálf er búin að vera að undirbúa ómskoðunina fyrir okkur.

When addressing a mixed-gender plural group (like a couple), remember that búinn takes the neuter plural form, which is also búin:

Have you been discussing the sex together?
Eruð þið búin að vera að ræða kynið saman?

Eventually, all that continuous waiting leads to an exciting moment back in the simple present tense:

The midwife shows us the ultrasound and we hear the heartbeat.
Ljósmóðirin sýnir okkur ómskoðunina og við heyrum hjartsláttinn.
