Comparamos el término fijo y el término variable.

Because Spanish usually leaves out subject pronouns when the verb already shows who is doing the action.

Comparamos already tells you the subject is we. So:

• Comparamos el término fijo y el término variable. = We compare / We compared the fixed term and the variable term.

You could say Nosotros comparamos..., but that normally adds emphasis, contrast, or clarity.

For example:

• Nosotros comparamos los datos, pero ellos los calculan.
  = We compare the data, but they calculate it.

Comparamos is the first person plural form of comparar.

That means it goes with we.

It can be:

• present tense: we compare
• or preterite: we compared

This is one of those forms in Spanish where the nosotros form looks the same in both tenses for many -ar verbs.

So by itself, comparamos is ambiguous. Context tells you which meaning is intended.

Examples:

• Normalmente comparamos precios. = We normally compare prices. → present
• Ayer comparamos precios. = Yesterday we compared prices. → preterite

You usually know from context.

Spanish often relies on:

• time words such as ayer, hoy, siempre, normalmente
• surrounding sentences
• the overall situation

In isolation, Comparamos el término fijo y el término variable could mean either:

• We compare the fixed term and the variable term
• We compared the fixed term and the variable term

If this is from an explanation, textbook, or procedure, it will often be understood as present.

Repeating el makes it clear that you are talking about two separate items:

• el término fijo
• el término variable

Spanish often repeats the article in coordinated noun phrases when each noun phrase is fully separate and specific.

So:

• el término fijo y el término variable sounds clear and natural

If you said el término fijo y variable, it could sound less complete or less precise in this context.

Because término is simply a masculine noun in Spanish. Its article is therefore el.

So you get:

• el término
• un término

And the adjectives must agree with it:

• el término fijo
• el término variable

This is grammatical gender, not biological gender.

In Spanish, adjectives often come after the noun, especially when they are describing a category or a distinguishing characteristic.

So:

• término fijo
• término variable

This is the normal order here.

Putting an adjective before the noun is sometimes possible in Spanish, but it often changes the tone, emphasis, or meaning. In technical or neutral language, the usual order is noun + adjective.

They are two different kinds of adjectives.

• fijo is a regular adjective that changes for gender and number:

  • fijo
  • fija
  • fijos
  • fijas

• variable is an adjective ending in -e, so it usually has the same form for masculine and feminine singular:

  • variable
  • variables

So here:

• el término fijo
• el término variable

If the noun were feminine:

• la tarifa fija
• la cantidad variable

The accent mark shows where the stress goes: TÉR-mi-no.

Without the accent, Spanish pronunciation rules would make you stress it differently. The written accent tells you the stressed syllable clearly.

So:

• término = stress on the first syllable

This is also helpful because Spanish spelling is very regular compared with English.

A rough pronunciation is:

• término ≈ TEHR-mee-no

More carefully in Spain:

• té as in a short teh
• r is tapped lightly
• mi like mee
• no like noh

And the stress is on the first syllable:

• TÉR-mi-no

Y means and.

So:

• el término fijo y el término variable = the fixed term and the variable term

Spanish normally uses y before words beginning with most sounds.

There is a special change to e before words that begin with an i sound:

• padre e hijo
• España e Italia

But that does not apply here, because variable does not begin with an i sound.

Yes. Both patterns are possible:

• comparar A y B
• comparar A con B

Both can mean to compare A and B / to compare A with B.

Your sentence uses:

• Comparamos el término fijo y el término variable.

That is perfectly natural.

You could also hear:

• Comparamos el término fijo con el término variable.

The version with con can sound a little more explicitly like we compare one thing with the other, but both are common.

Because the sentence is talking about one fixed term and one variable term, not several of each.

So:

• el término fijo = the fixed term
• el término variable = the variable term

If you were talking about more than one of each, you would use the plural:

• Comparamos los términos fijos y los términos variables.

To some extent, yes, but this version is the most neutral and natural:

• Comparamos el término fijo y el término variable.

Spanish often allows some word-order variation, but not every option sounds equally natural.

This sentence has:

• an omitted subject
• the verb first
• then the objects

That works very well in explanations, instructions, and general statements.

A version with Nosotros would also be possible:

• Nosotros comparamos el término fijo y el término variable.

But that adds emphasis to we.

It is neutral in register.

Nothing in it is especially formal or especially informal. It sounds like standard written or spoken Spanish, especially in an explanatory, academic, or technical context.

For example, it would fit well in:

• a maths explanation
• an economics class
• a utility bill explanation
• a textbook or worksheet

In this kind of context, término often means term, component, or part of a calculation, formula, or charge.

So término fijo and término variable are often used for:

• parts of a bill
• parts of a formula
• fixed and variable components in economics or maths

The exact English translation depends on context, but grammatically the sentence is straightforward:

• Comparamos = we compare / we compared
• el término fijo = the fixed term
• y el término variable = and the variable term
