Learn Hardcore Swedish: Vi planerar projektet tillsammans på datorn. - We are planning the project together on the computer.

Swedish present tense covers both English present simple and present progressive. So bold Vi planerar projektet can mean “We plan the project” or “We are planning the project,” depending on context. Time words make it clear if needed:

bold Nu planerar vi projektet (right now)
bold Vi planerar projektet i morgon (we’re planning it tomorrow)

Why bold projektet and not bold ett projekt or just bold projekt?

bold projektet = “the project” (a specific one both speaker and listener know about).
bold ett projekt = “a project” (non-specific).
bare bold projekt is plural indefinite (“projects”), not singular. You can’t use bare bold projekt for a single project.

What gender is bold projekt and how do I inflect it?

bold projekt is an ett-word (neuter). Common forms:

Singular indefinite: bold ett projekt
Singular definite: bold projektet
Plural indefinite: bold projekt
Plural definite: bold projekten

Do I need bold tillsammans med someone, or can bold tillsammans stand alone?

bold tillsammans can stand alone to mean “together” (collaboratively). Use bold tillsammans med when you name who you’re together with:

bold Vi planerar projektet tillsammans.
bold Vi planerar projektet tillsammans med Anna.

Can I use bold ihop instead of bold tillsammans?

Yes. bold ihop is a common, slightly more informal synonym:

bold Vi planerar projektet ihop (≈ together). bold tillsammans is neutral and works in all contexts; bold ihop is friendly/colloquial.

Is the word order with bold tillsammans and bold på datorn fixed?

No, there’s some flexibility. All of these are acceptable, with similar meaning:

bold Vi planerar projektet tillsammans på datorn. (neutral)
bold Vi planerar projektet på datorn tillsammans. (also natural)
bold Tillsammans planerar vi projektet på datorn. (fronted for emphasis; see V2 below) bold Vi planerar tillsammans projektet på datorn is possible but less idiomatic; placing bold tillsammans right after the verb can sound a bit stiff unless you’re emphasizing the manner early.

Why bold på datorn and not bold i/vid/med datorn?

bold på datorn = “on the computer,” either doing it digitally or that the result is on the computer. This is the idiomatic choice here.
bold vid datorn = “at the computer” (physically sitting by it); focuses on location rather than the medium.
bold i datorn = literally “in the computer” (inside the machine); only for very literal contexts (e.g., a part inside).
bold med datorn = “with the computer” (using it as a tool); possible but less natural here than bold på datorn.

Does bold på datorn mean one specific computer?

It can, but Swedish often uses the definite form for devices as a medium, even when no particular device is meant (similar to bold på tv:n, bold på mobilen). If you truly mean an unspecified computer, you can say bold på en dator or, for online work, bold online / bold på nätet.

Why not bold planerar för/på projektet?

bold planera is normally transitive: bold planera + direct object.

bold Vi planerar projektet (correct) bold planera för means “plan for” in the sense of making arrangements in support of something: bold Vi planerar för projektet (we’re doing preparatory planning for it). bold planera på is not used in standard Swedish for this meaning.

Can I front something for emphasis, and what happens to the verb?

Yes. Swedish main clauses follow the V2 rule: the finite verb must be in second position.

bold Tillsammans planerar vi projektet på datorn. (adverbial first → verb second)
bold På datorn planerar vi projektet tillsammans.
bold Projektet planerar vi tillsammans på datorn. All are grammatical and used for emphasis or flow.
