Questions & Answers about Rafhlaðan virkar núna.

What does the ending -an in "rafhlaðan" mean, and why not "rafhlaða"?

The ending -an is the suffixed definite article for feminine nouns ending in -a. It corresponds to English “the.” The base word is rafhlaða (battery). When you add the article -in to a noun ending in -a, the i drops, giving -an:

• rafhlaða + -in → rafhlaðan = “the battery”
• Without it: rafhlaða = “a battery”

What gender is rafhlaða, and which pronoun should I use for it?

Rafhlaða is feminine. Refer back to it with hún (she/it). Example: Hún virkar núna.

How is virkar formed? What are the present-tense forms of virka?

Virka is a regular weak verb. Present tense:

• ég virka
• þú virkar
• hann/hún/það virkar
• við virkum
• þið virkið
• þeir/þær/þau virka

Past (for reference): ég virkaði, hún virkaði, við virkuðum, etc. Example: Rafhlaðan virkaði (The battery worked).

Can I say “is working now” in Icelandic, like “Rafhlaðan er að virka núna”?

Normally no. For states like “to function,” Icelandic uses the simple present: Rafhlaðan virkar núna.

Where does núna go? Are there other acceptable positions?

• Neutral: Rafhlaðan virkar núna.
• To emphasize the time: Núna virkar rafhlaðan.
• With time-limited negation: Rafhlaðan virkar ekki núna. (“doesn’t work right now”) Avoid placing núna between subject and verb in the affirmative.

How do I negate it?

Put ekki after the verb:

• Rafhlaðan virkar ekki.
• With a time adverb: Rafhlaðan virkar ekki núna. For “no longer,” use ekki lengur: Rafhlaðan virkar ekki lengur.

What exactly does virka mean here, and how is it different from vinna, ganga, or virkja?

• virka = to function/work (as in not broken). Devices, systems, medicines: Tölvan virkar.
• vinna = to work (do a job/labor). Not used for devices: Ég vinn á spítalanum.
• ganga = to run/operate/go. Used of machines running: Vélin gengur vel (“The machine runs well”). For a battery, prefer virka.
• virkja = to activate/harness (transitive): að virkja rafmagn, að virkja lykil (“activate a key”).

Any pronunciation tips for this sentence?

• Primary stress on the first syllable of each word.
• r is tapped/rolled.
• ð in rafhlaðan sounds like the “th” in “this.”
• ú in núna is like “oo” in “food.”
• hl is pronounced with a voiceless l (a faint h + l sound): hla-.
• Rough guide: “raf-hla-than vir-kar NOO-na” (with i in virkar like the i in “bit”).

Can I use nú instead of núna? Any difference?

Yes. Both mean “now.” Núna is the everyday neutral choice. Nú is shorter and can feel a bit more formal or rhetorical, and it’s also used as a discourse particle (“well/now”). Rafhlaðan virkar nú is fine but less conversational than Rafhlaðan virkar núna.

Is rafhlaða always the right word for “battery”?
