False In Spanish, the verb "poder" (to be able/can) undergoes an o to ue stem change in certain present tense forms.
How is this false
This change affects the yo (I) and tú (you, informal singular) forms: "puedo" (I can) and "puedes" (you can).
However, the other present tense forms (él/ella/usted - he/she/you formal, and ellos/ellas/ustedes - they/you all) do not undergo this stem change, maintaining the regular stem "pod-": "puede" (he/she/you can), "pueden" (they/you all can).
