1 in addition to something else you have mentioned; as well as: She owns several houses in Leeds and also has business interests in Manchester. | I'll take the car because it's a long walk from the station; also the forecast is for rain. | We can supply samples and there other laboratories that can be consulted also. | not only...but also..: The report has not only attracted much attention but also some sharp criticism.2 used when saying that the same thing is true about another person or thing: My girlfriend was also called Helen.-see moreover USAGE NOTE: ALSO WORD CHOICE: also, too, as well, either, neither When you want to say that something exists or happens in addition to something else, too and as well are more common than also in informal and spoken English. In a scientific report you might see: The acid also reacts with the coating. Or it can be used as part of a more formal request: Could you also type this please? In spoken English, as well is very common: Can you come too/as well? | I was so busy I missed lunch and dinner as well. If the verb is negative, you use either: "I don't like grammar." "I don't like it either". (NOT I don't like it too or I don't also like it, though I also don't like it is possible, but more formal). In informal English people usually say not...either rather than neither: She won't come with me or with Grandpa either (if here you said: She will neither come with me nor with Grandpa, it would sound very formal and unnatural). GRAMMAR Also usually comes after the first auxiliary or modal verb and before the main verb: The school also has a gymnasium (NOT usually The school has also a gymnasium).| He can also sing a little (NOT usually ...also can).| Many were bringing up children and also working. Also usually follows the verb to be where it is used alone as a main verb: Osaka is also worth a visit. Also is not usual at the end of a sentence, where too and as well are common.
