Anónimo preguntó: Hi Mr Welsch! I couldn't find any agreement about the meaning of TO LOOK UP between some native speakers. At the diccionary you can find things like "mirar hacia arriba" "buscar en el diccionario" but also "mejorar", is that correct? Bussiness are looking up = Los negocios están mejorando. Thank you very much!

Yes, they’re all correct! Look up is like a lot of phrasal verbs in having multiple meanings.

She looked up and saw a bird flying overhead. = mirar hacia arriba

I looked up her phone number. = buscar algo en un libro o en internet.

Things are looking up. = Las cosas están mejorando, estoy optimista.

Tu ejemplo sería Business is looking up. Business es singular, aunque termine con -s.

Gracias por la pregunta!
