Que Eu Saiba: Answer Within the Limits of What You Know
Limit the knowledge behind the answer
Que eu saiba means “As far as I know.” Que eu saiba, o jantar está marcado presents the plan as true within your current knowledge. It leaves room for information you have not received. The expression does not necessarily mean you think cancellation is likely; it identifies the limit of your information.
Que eu saiba, o jantar ainda está marcado.
As far as I know, dinner is still on.
Limits the assertion to current knowledge.
Ninguém me avisou de uma mudança.
Nobody has told me about a change.
Reports the absence of notice.
Keep the expression together
Saiba is a present-subjunctive form of saber. In this short expression, que eu saiba works as a conventional frame around a statement. You do not need to rebuild the entire sentence as a question. Place it at the beginning for an easy pattern, then state the information you believe is current.
Não confirmei com a Ana hoje.
I have not checked with Ana today.
Makes a relevant information limit explicit.
Vou confirmar com ela e te aviso.
I will check with her and let you know.
A future action rather than a completed check.
Do not turn no notice into no change
Ninguém me avisou de uma mudança reports that you received no notice. Não houve mudança asserts that no change happened. Those are not the same claim. Que eu saiba can help distinguish them, but an added explanation is useful when somebody might otherwise rely on your answer as final confirmation.
Não sei se mudou.
I do not know whether it changed.
Useful when you lack a basis for a positive claim.
Confirmei agora: o jantar continua marcado para as sete.
I just checked: dinner is still arranged for seven.
A specific update after an actual check.
Offer a check when a firm answer is needed
The original dialogue below keeps the current answer and the next action separate. Vou confirmar com a Ana is a promise to check, not proof that checking has happened. After checking, report the actual result. Do not keep the same hedge automatically if you now have a direct answer relevant to the question.
Amigo: O jantar ainda vai acontecer?
Is dinner still happening?
Você: Que eu saiba, sim. Ninguém me avisou de uma mudança.
As far as I know, yes. Nobody has told me about a change.
Amigo: Você confirmou hoje?
Did you check today?
Você: Ainda não. Vou confirmar com a Ana e te aviso.
Not yet. I will check with Ana and let you know.
Use a clear unknown when appropriate
If you have no useful information, não sei may be clearer than que eu saiba followed by a guess. The expression works best when you have a basis for the statement but cannot rule out later developments. Be specific about that basis: the last arrangement, an earlier message, or what you were told.
Practice before opening the answers
These are original written practice activities. Try a reply first, then compare the suggested answer and explanation. Other answers can work when they keep the intended meaning.
- Original practice: The last plan was dinner at seven, but you have no recent confirmation. Answer with the knowledge limit.
Suggested answer and explanation
Que eu saiba, o jantar continua marcado para as sete.
The statement retains the last known plan without claiming access to every later development.
- Original practice: You received no change notice. Report only that fact.
Suggested answer and explanation
Ninguém me avisou de uma mudança.
No notification to you does not establish that nobody changed anything.
- Original practice: You have no information about whether a new event is happening. Choose a clearer answer than a qualified guess.
Suggested answer and explanation
Não sei se vai acontecer. Posso perguntar.
A direct unknown is more accurate when there is no prior information to qualify.
- Original practice: You actually checked and the host confirmed seven. Give the new result.
Suggested answer and explanation
Confirmei com a Ana agora: o jantar é às sete.
The completed check and named result replace the earlier information gap with a specific update.
