## Vocab.get_vector {#get_vector tag="method" new="2"}
Retrieve a vector for a word in the vocabulary. Words can be looked up by string
or hash value. If no vectors data is loaded, a `ValueError` is raised.
If `minn` is defined, then the resulting vector uses Fasttext's
subword features by average over ngrams of `orth`. (Introduced in spaCy `v2.1`)
or hash value. If no vectors data is loaded, a `ValueError` is raised. If `minn`
is defined, then the resulting vector uses [FastText](https://fasttext.cc/)'s
subword features by average over ngrams of `orth` (introduced in spaCy `v2.1`).

| Name | Type | Description |
| ----------- | ---------------------------------------- | ---------------------------------------------------------------------------------------------- |
| `orth` | int / unicode | The hash value of a word, or its unicode string. |
| `minn` | int | Minimum n-gram length used for Fasttext's ngram computation. Defaults to the length of `orth`. |
| `maxn` | int | Maximum n-gram length used for Fasttext's ngram computation. Defaults to the length of `orth`. |
| **RETURNS** | `numpy.ndarray[ndim=1, dtype='float32']` | A word vector. Size and shape are determined by the `Vocab.vectors` instance. |
