Why is there no word for a or the? Why isn’t it The exercise is good or An exercise is good?

Icelandic does not have a separate word for the indefinite article a/an, and the definite article the is usually attached to the noun as an ending.

• No article (general statement):

  • Æfing er góð. → Exercise / Practice is good. (in general)

• Definite article (attached):

  • Æfingin er góð. → The exercise is good.
    
    • æfing
      • -in (feminine definite ending) → æfingin

So the original sentence without any article is a general statement about exercise/practice, not about one specific exercise.

What gender is æfing, and why does that matter for góð?

Æfing is a feminine noun.

The adjective góður (good) changes its form to agree with the noun in gender, number, and case:

• Masculine nominative singular: góður
• Feminine nominative singular: góð
• Neuter nominative singular: gott

Because æfing is feminine and is the subject in the nominative case, the adjective must also be feminine nominative, so we get:

• Æfing er góð. → góð (feminine form)

If the noun were masculine, you would say, e.g.:

• Matur er góður. → Food is good.

And if it were neuter:

• Veður er gott. → The weather is good.

---

Could it be Æfing er góður or Æfing er gott?

No. That would be ungrammatical, because the adjective must match the gender of the noun:

• æfing → feminine → góð
• góður → masculine form → does not match
• gott → neuter form → does not match

So for this noun, only Æfing er góð is correct.

---

What is er exactly? Is it like is in English?

Yes. Er is the 3rd person singular present form of the verb að vera (to be).

Basic forms of að vera in the present tense:

• ég er – I am
• þú ert – you are (singular)
• hann / hún / það er – he / she / it is
• við erum – we are
• þið eruð – you are (plural)
• þeir / þær / þau eru – they are

So Æfing er góð. literally corresponds to Exercise is good.

---

What is the normal word order here? Could you say Góð er æfing instead?

The normal, neutral word order in Icelandic (as in English) is Subject – Verb – Complement:

• Æfing (subject)
• er (verb)
• góð (subject complement / predicate adjective)

So Æfing er góð. is the standard way to say it.

You can say Góð er æfing in poetry or for emphasis, but it sounds marked or stylistic, not like an ordinary neutral statement.

How do you pronounce Æfing er góð?

    • verb: er (singular)

Is góð only used after er, or can it come before the noun, like a good exercise?

Góð can appear both:

1. Predicatively (after er, like in the sentence you gave):

   • Æfing er góð. → Exercise is good.

2. Attributively (directly before a noun):

   • góð æfing → a good exercise / a good practice
   • Þetta var góð æfing. → That was a good exercise.

The form góð stays feminine nominative singular in both cases, because it is describing a feminine nominative singular noun (æfing) either way.
