📚 Los verbos yo-go — The Yo-Go Verbs

These Higher verbs share one special property: their yo form inserts a -g- before the ending, making them look irregular only in the first person. Once you know the yo form, the rest follows the standard -er/-ir endings exactly.

Infinitivo	yo	tú / él / nosotros / ustedes	Note
salir (to go out)	salgo	sales · sale · salimos · salen	Pure yo-go
traer (to bring)	traigo	traes · trae · traemos · traen	Pure yo-go
poner (to put / place)	pongo	pones · pone · ponemos · ponen	Pure yo-go
seguir (to follow / continue)	sigo	sigues · sigue · seguimos · siguen	Yo-go + e→i stem change

⭐ Key rule

All these verbs are regular EXCEPT the yo form. Once you know the yo form, the rest is entirely predictable. Note: seguir has two irregularities — the yo-go g-insertion AND an e→i stem change throughout. The u in the spelling is silent; it exists purely to keep the g hard before -o and -e.

Two more higher-tier irregulars Higher

These two do not follow the yo-go pattern but are equally essential:

Infinitivo	yo	tú / él / nosotros / ustedes	Irregularity
conocer (to know — people/places)	conozco	conoces · conoce · conocemos · conocen	zc-insertion before -o
saber (to know — facts/skills)	sé	sabes · sabe · sabemos · saben	Unique yo form
