The placement of only as a modifier is more a matter of style and clarity than of grammatical rule. In a sentence like The doctor examined the children, varying the placement of only results in quite different meanings: The doctor only examined the children means that the doctor did nothing else. And The doctor examined only the children means that no one else was examined. Especially in formal writing, the placement of only immediately before what it modifies is often observed: She sold the stock only because she needed the money. However, there has long been a tendency in all varieties of speech and writing to place only before the verb ( She only sold the stock because she needed the money ), and such placement is rarely confusing.

Word Origin for only
Old English ānlīc, from ānone + -līc-ly ²
usage
In informal English, only is often used as a sentence connector: I would have phoned you, only I didn't know your number. This use should be avoided in formal writing: I would have phoned you if I'd known your number. In formal speech and writing, only is placed directly before the word or words that it modifies: she could interview only three applicants in the morning. In all but the most formal contexts, however, it is generally regarded as acceptable to put only before the verb: she could only interview three applicants in the morning. Care must be taken not to create ambiguity, esp in written English, in which intonation will not, as it does in speech, help to show to which item in the sentence only applies. A sentence such as she only drinks tea in the afternoon is capable of two interpretations and is therefore better rephrased either as she drinks only tea in the afternoon (i.e. no other drink) or she drinks tea only in the afternoon (i.e. at no other time)
Old English ænlic, anlic "only, unique, solitary," literally "one-like," from an "one" (see one) + -lic "-like" (see -ly (1)). Use as an adverb and conjunction developed in Middle English. Distinction of only and alone (now usually in reference to emotional states) is unusual; in many languages the same word serves for both. German also has a distinction in allein/einzig. Phrase only-begotten (mid-15c.) is biblical, translating Latin unigenitus, Greek monogenes. The Old English form was ancenned.
