Can I use this sign to mean 'empty'?
Yes, this exact sign is also widely used to mean 'empty,' 'bare,' 'bald,' or 'blank.' In ASL, a single sign can often translate to several English words with similar underlying concepts. The context of your sentence—whether you are talking about a lack of skills, an empty box, or a bare wall—will make your intended meaning perfectly clear to the person you are signing with.
Do I need to touch my chest when signing this?
Yes, making physical contact is an important part of executing this sign correctly. As your hands move downward, your bent middle fingers should lightly brush against your chest. The tactile feedback of the middle fingers sliding down your clothing helps distinguish this sign from others and emphasizes the feeling of emptiness or bareness associated with the word.
Is there another way to sign 'lack'?
Yes, ASL is a rich language with multiple ways to express similar ideas depending on the exact context. For instance, you might see 'lack' signed by tapping the side of the index finger against the chin, which is also used for 'missing' or 'disappointed.' However, the chest-brushing sign shown here is an excellent, versatile choice for showing a complete absence, emptiness, or a zero-quantity state.
