Deducimos el patrón.

Deducimos is the 1st person plural present indicative form of deducir.

So it means the action is being done by we.

• deducir = infinitive
• deducimos = we deduce

In this sentence, the verb is in a normal statement form, not a command, not the subjunctive, and not the past.

Because Spanish often omits subject pronouns when the verb ending already makes the subject clear.

The ending -imos tells you the subject is we.

So both of these are possible:

• Deducimos el patrón.
• Nosotros deducimos el patrón.

The version without nosotros is more natural in many contexts.
You would usually add nosotros only for emphasis, contrast, or clarity.

For example:

• Nosotros deducimos el patrón, no ellos.
  = We deduce the pattern, not them.

In standard peninsular Spanish, c before i is pronounced like the th in think.

So deducimos sounds approximately like:

• de-du-THI-mos

A more detailed pronunciation is roughly:

• de-du-θi-mos

The stress falls on ci:

• de-du-CI-mos

Also, in natural speech in Spain, the d between vowels can sound softer than in English.

Because Spanish usually uses an article with a noun in a full sentence when talking about a specific thing.

Here, el patrón means the pattern as the direct object of the verb.

So:

• Deducimos el patrón. = normal full sentence

If you said just Deducimos patrón, it would sound incomplete or unnatural in standard Spanish.

Spanish generally uses articles more often than English in some situations, and in this sentence the article is the normal choice.

Because the stress falls on the last syllable:

• pa-TRÓN

In Spanish, if a word ends in n, s, or a vowel, the stress normally falls on the second-to-last syllable unless there is a written accent.

Since patrón ends in n but is stressed on the last syllable, it needs the accent mark.

Without the accent, patron would be pronounced differently.

Patrón is masculine, which is why it takes el:

• el patrón

In this sentence, you know the gender from the article.

The ending -ón does not automatically guarantee gender in every case, but many nouns ending in -ón are masculine. Still, the safest guide is the article and dictionary form.

It is not completely regular.

In the form used here, deducimos, it looks regular enough, but deducir has irregular forms in other parts of the conjugation.

For example:

• yo deduzco
• tú deduces
• nosotros deducimos

And in the preterite:

• yo deduje
• nosotros dedujimos

So deducimos itself is straightforward, but the verb as a whole has irregular patterns that you will need to learn.

No. In this case, deducimos is present, not past.

That is useful because some Spanish verbs do have forms that look the same in present and preterite, but this verb does not work that way here.

For deducir:

• present: deducimos = we deduce
• preterite: dedujimos = we deduced

So if you see deducimos, you should understand it as present indicative.

Yes, but Deducimos el patrón is the most neutral and natural order.

Spanish word order is more flexible than English, but changes in order usually add emphasis or sound more marked.

For example:

• Deducimos el patrón. = neutral
• El patrón lo deducimos. = the pattern, we deduce it / more emphasis on the pattern

So for a simple statement, the original order is the best one to learn first.
