| GUH Palm | LUH Palm | Second | Second | GUH Palm | LUH Palm |
| GUH Position | LUH Separation | Third | Third |

### Number

(ASL gloss: ONE)
* one; 1

#### Usage notes

Some people always sign the number 1 with the palm forward. For others, however, the palm faces back (i.e., as 1@Side-PalmBack) for the actual number 1 but the palm faces forward when used as a part of a longer number like 555-1234, as a time (i.e. one o'clock), and in certain other numeral-incorporating constructs.

* Next number: 𝠎𝪜 (“two, 2”)

### Pronoun

(ASL glosses: CL-1, CLASSIFIER-1)
* the person; ASL classifier used for a standing person.
* the long, thin, vertical thing; ASL classifier used for a long, thin, vertical object, e.g. a telephone pole or a tree

#### Usage notes

* (the person, classifier for a standing person): As a person classifier, the pad of the index finger represents the face and the lower phalanges represent the lower portion of the body. The finger can thus be moved or turned in various ways to represent corresponding movements of the person. For example, if the hand slowly bounces while moving forward and then turns to the left, it means something like “the person was walking along leisurely and then made a left turn.”
* To show interactions with other classifiers, the nondominant hand is often used as this classifier:
    3@InsideChesthigh-FingerAcross-1@CenterChesthigh-PalmForward S@Finger-PalmBack-1@CenterChesthigh-PalmForward
    “[And then] the vehicle crashed into the pole.”
